I built a form in Cognito Forms for employees to reserve company vehicles. The following are important fields on the form:
Employee Name
Employee Email
Vehicle (selection)
Pick Up Date = date the user will get the car
Mileage = how many miles the user put on the car, entered after returning the car
We want to restrict the user from entering a new car reservation if they have a past entry that has not had Mileage entered. I was considering using a calculated field of some kind and then using the quantities feature to restrict duplicate entries but not sure what could be used in the form as comparison for duplicates. I know that currently Cognito Forms does not have a method for doing lookups of previous entries or else there wouldn't be a question. Has anyone else found a workaround before?

First off, I am new at this. Secondly, yes I am working with access 2003 and this is not by choice. It is the program that my job has provided to me, so I am stuck using it.
Question: I have created a form with a subform in access2003. The form has three fields: State, Year and CompanyName.
The sub form then lists three fields: CompanyID, Date, and AmtPaid (in dollars).
I would like for the subform to autopopulate/autofill in the CompanyID in the subform each time I have users enter a new line of data in to the subform.
For example: I choose the following in the form...State=PA, Year=2017, CompanyName=ABC (ID=2).
I then can enter values in to my subform...CompanyID=2, Date=3/1/17, AmtPaid=$10.00.
When I go to enter a new line of data, for example the amount paid for the same company on 4/1/17, I would like for the CompanyID to automatically fill in "2". My goal is for this field to autofill for each company ID since I am planning on avoiding user error and also planning on hiding this field.
I understand the default assignment in the properties window of the field, but if i enter in the number "2", then "2" will be entered by default for all companys, not just for company ABC. I believe i have to write some sort of code that references a previous field or the first field in the subform, so that the new line copies what has been entered previously.
Any help is much appreciated in advance.
I'm looking for some best practices when it comes to modeling confidential hierarchical data in general and specifically with DynamoDB.
The scenario is best explained with an example:
Let's say we have a number of users. Each user has a number of products. Each product consists of a number of parts.
Typical use cases:
List all products for a given user
List all parts for a given product
So far I have modeled this in DynamoDB like this:
Users
----------------
HashKey: UserId
Products
-------------------
HashKey: UserId
RangeKey: ProductId
Parts
-------------------
HashKey: ProductId
RangeKey: PartId
The data is confidential and accessed through authenticated REST endpoints where an authentication token can be mapped to a UserId. Each user may be allowed to view other users' data through some group concept.
Listing all products for a given user is simple since UserId is a key in the products table:
GET /users/111/products becomes a simple Query(Table=Products, UserId=111)
But consider the case of listing all parts for a given product:
GET /users/111/products/222/parts
If I simply do a Query(Table=Parts, ProductId=222) then I will get the desired data fast, but I am not protecting against other users querying for data belonging to user 111, provided they somehow know about ProductId 222 (in reality, ID:s will of course be UUID:s or similar so not so easily guessable):
GET /users/119/products/222/parts
... would result in malicious user 119 retrieving data that doesn't belong to him, provided nothing is done to address this.
So here I imagine I need to do something like one of these:
First make another query to make sure product 222 in fact belongs to the given user
Duplicate the UserId in the Parts table and include it in the query condition (which basically means it will match either all rows or no rows when scanning through the set identified by ProductId): Query(Table=Parts, ProductId=222, UserId=111)
Use UserId as the hash key also in the Parts table and instead keep ProductId as a secondary index
Use a composite HashKey such as UserId_ProductId ("111_222") on the Parts table
If I need to return a 401 as opposed to just empty data, option 1 seems like the only approach. But if we imagine a deeper hierarchy of data, e.g. "users having inboxes having messages having parts having attachments" it seems this approach could eventually be expensive (listing all attachments for part P might result in a query to check that part P belongs to message M, that message M belongs to inbox I and that inbox I belongs to user U, and so on).
Does anyone have any good arguments for which approach is most favorable? Or am I doing something stupid and should be modeling my data in some other way completely?
I have a specific question regarding the utilization of three tables in a database. Table 1 is called Personnel, and lists the names of the staff.
Tables 2 and 3 are identical, just listing two different types of overtime (long and short), along with the hours of the OT, Date of the OT, and Assigned to/Picked fields that are empty.
Here is the idea, I just dont know how to implement it. I would like to create a form for people to enter their OT picks, then automatically move to the next person on the list. So Rich Riphon, as an example, would be up first, would click on the link I would send, and a form would open up, showing his name, populated by the first table, and showing two drop down menus, populated from the Long OT and Short OT tables. He would select one from each (or None, which would be a option) and Submit it.
The form action would be to place his name in the Assigned field for the OT he picked, and place a Yes in the Picked field.
When the next person in the list opens the form, it has moved down to number 2 on the Personnel list, Cheryl Peterson, and shows her the remaining OT selections (excluding those that have a Yes in the Picked column).
Any suggestions or comments or better ways to do this would be appreciated.
First, I don't think ms access would be able to (easily) kick off the process based on a hyperlink. You may be able to do something by passing a macro name to a cmd prompt but it would take some mastery to get it working properly. Could you instead create a login form to get the current user? If you do that you don't really need to display the personnel list, just keep track of who has not yet responded to the OT request. Essentially at that point all you would need on your form is a listing of the available OT and a button that creates the assignment. Also it may be easier (and a better design) to only have one table for the OT listings and add a column for the type of overtime (long/short).
What if Cheryl isn't the 2nd person to get the form? Your concept goes out the window.
Instead, I would keep a table of all user names, and their security level. managers can see everything, individual users can only see their record. This would be done by using a query behind the OT Picks form, and either filtering by the current user or not filtering at all. I have done many of these types of "user control" databases and they all have worked well.
As for the actual OT tracking, I agree with Steve's post in that it should be done in one table This would be the preferred method of a concept referred to as "normalizing data". You really want to store as little data as possible to keep the size of your database down. As an example, your Login table would have the following fields:
UserID
FirstName
LastName
SecurityLevel
Address1
Address2
City
State
Phone
Etc... (whatever relevant info pertains to that person)
Your OT table would look like this:
UserID
OTDate
OTHours
OTType
Etc... (whatever else is relevant to OT)
You would then join those 2 tables on the UserID fields in both tables any time you needed to write a query to report OT hours or whatever.
I am trying to work around a limitation that Filemaker 12 seems to have. In a value list that links to an ODBC attached SQL Server database, it doesn't display every piece of data. If there are 2 people with the same last name for example, it only displays the first person with that last name in the list. This is verified by the following in the Filemaker documentation (which I found after a lot of digging)
If the value list is defined to display information from two fields, items will not be duplicated for the field on which the value list is sorted. For example, if the value list displays information from the Company field and the Name field, and if the values are sorted by the Company field, only one person from each company will appear in the value list.
Portals on the other hand will find all the related data, I just don't understand how do something with the data once I get it in the portal. I essentially thus wish to use a portal AS my drop-down value list, and then to use it as I would have a value list (which is then to act as the key to do the rest of the lookups on the page to fill out the invoice.
The major issue here (other than this maddening choice Filemaker seems to make) is that the external file I am pulling the data from is an ODBC mounted SQL Server file, so I can't do something easy like a calculated field which would give me last name & " " & first which would make almost every person unique. Filemaker won't let me do that because it says I can't do that with a field that is not indexed. Any help would be greatly appreciated!
Assuming that we're starting with table MyTable and we're trying to get a ID from the People table for the selected person, which we'll call ID so that we can put it into MyTable::PersonID
Start by creating a new Table Occurrence of your People table and call it PeopleWhoCanBeSelected. If you want every person in the People table you can connect it to MyTable with the X relationship. If you want to show just a subset of the people you can build a different relationship.
Now, on a layout displaying records from MyTable you will make a portal showing records from the PeopleWhoCanBeSelected table.
In the portal put a button. When that button is pressed use the Set Field script step:
Set Field MyTable::PersonID to:
PeopleWhoCanBeSelected::ID
That should do it. You can make the button an invisible overlay on the entire portal record if you like, so that the user clicks on "the name" instead of "the button next to the name".
Now, if you want to pull additional data through to the MyTable record, you'll need to create a second Table Occurrence, called People with the relationship MyTable::PersonID = People::ID. Then you can get information on the specifically chosen person through that relationship.
I have created an adaptation of the 'Goods' database that includes a quote feature. The user selects the customer (customer table), Product (product table), qty, discount ect.
The chosen entities then get saved to the quotes table and there is a 'print' function on form.
Whilst the information can be saved and the quote prints via a quote report, I'm having major difficulty in finding a way to add multiple products to a single quote.
The main objective is to be able to select various products and add their total price (product after addition of qty, discount) to a SUB TOTAL
Quote total is therefore the formula Tax+Shipping+SubTotal
any takers? :)
Hi guys,
Thanks for the response I really appreciate it. As for tax and shipping, they are just added in the form and are not pushed from anywhere else in the database. Its simply a type in form and display on report sort of thing. As you said in the answer, HansUp, the salesperson will compute it seperately and just input it.
As for tax, products will be shiped globally so the tax/vat shall be computed seperately also.
Also, each table DOES have its own unique ID.
More to the point of having QuoteProducts. I can't seem to get my head around it! Are you saying that whatever products are chosen in QuoteProducts will create a QuoteProd_ID and then that ID's total price will therefore be added to the Quote?
I tried making a subform before but through the 'multiple records' form but obviously every selection made its own ID. Is there any way you could elaborate on the Quote products part and how it allows multiple records to store to one ID? Without understanding it i'm pretty much useless.
In addition, how the multiple records are then added up to make the subtotal also baffles me. Is that done in the Quote form?
Edit 2
HALLELUJAH.
It works! I created a sum in a textbox on the footer of the subform and then pushed that into subtotal :)
I do have one slight issue:
I made a lookup&relationship for the ListPrice. I don't think its the correct way to do it as it comes up with the price of every light (i.e 10 products priced £10, £10 shows up ten times in dropdown).
Can you guys help?
List Price Problem
here's what i've tried:
1) Create >Client>Query Design
2) Show Products, QuoteDetails. For some reason, it automtically comes up with ListPrice, ProductID (as it should) and Product Name linked to ID in Products
3) Delete links with ListPrice and ProductName.
4) Show all in quoteDetails (*)
5) Create Multiple Items form
Doesnt work! What am I doing wrong?
I'm extremely grateful for both your help. If I can do anything, just shout.

In addition to HansUp's stellar answer, you might be interested in DatabaseAnswers.org. They have a number of data models for free that might provide additional insight to your situation and possibly serve as inspiration for future projects you may encounter.
Edit 1
Forget about the form and report for a moment - they are important but not as important as the data and how you store the data.
In your current design, you have a quotes table presumably with an autonumber key field. For the purposes of this answer, this field is named Quote_ID.
The quotes table, as HansUp suggested, should store information such as the Customer_ID, Employee_ID, OrderDate and perhaps even a reference to a BillingAddress and ShippingAddress.
The quotes table SHOULD NOT store anything about the products that the customer has ordered as part of this quote.
Instead, this information should be stored in a table called QuoteProducts or QuoteDetails.
It's structure would look something like the following:
QuoteDetails_ID --> Primary Key of the table (autonumber field)
Quote_ID --> Foreign key back to the Quotes table
Product_ID --> Foreign key back to Products table
Quantity
UnitPrice
You may also want to consider a field for tax and a separate field for shipping per line item on the quote. You will inevitably run into situations where certain items are taxable in some locations and not others, etc.
This design allows a particular quote to have any number of products assigned to the quote.
Returning to your form \ reports, you would need to change your existing forms and reports to accomodate this new table design. Typically one would use a main form for the quote itself, and then a subform for the quote details (item, price, quantity, etc).
To get the quote total, you would sum the items in QUoteDetails for a particular Quote_ID.
You may also want to check out the Northwind sample database from Microsoft. From what I recall Northwind had a sample Orders system that might help make these ideas more concrete for you by seeing a working example.
For the first 3 tables mentioned in your comment, each should have a primary key: Customers, customer_id; products, product_id; and employees, employee_id.
The quotes table will have its own primary key, quote_id, and will store customer_id and employee_id as foreign keys. (I'm assuming you want employee_id to record which customer representative/salesperson created the quote.) You may also decide to include additional attributes for each quote; date and time quote prepared, for example.
The products offered for quotes will be stored in a junction table, QuoteProducts. It will have foreign keys for quote_id and product_id, with one row for each product offered in the quote. This is also where you can store the attributes quantity and discount. An additional field, unit_price, can allow you to store the product price which was effective at the time the quote was prepared ... which would be useful in case product prices change over time. I don't know whether tax should be included in this table (see below).
I also don't know how to address shipping. If all the products associated with a quote are intended to be delivered in one shipment, shipping cost could be an attribute of the quotes table. I don't know how you intend to derive that value. Seems like it might be determined by shipping method, distance, and weight. If you have the salesperson compute that value separately, and then input the value, consider how to handle the case where the product selection changes after the shipping fee has been entered.
That design is somewhat simplistic, but might be sufficient for the situation you described. However, it could get more complex. For example, if you decide to maintain a history of product price changes, you would be better off to build in provisions for that now. Also, I have no idea how tax applies in your situation --- whether it's a single rate applied to all products, varies by customer location, varies by type of customer, and/or varies by product. Your business rules for taxes will need to be accommodated in the schema design.
However, if that design works for you (test it by entering dummy data into the tables without using a form), you could create a form based on quotes with a subform based on QuoteProducts. With quote_id as the link master/child property, the subform will allow you to view all products associated with the main form's current quote_id. You can use the subform to add, remove, and/or edit products associated with that quote.
Not much I can say about the report. There is a lot of uncertainty in the preceding description. However, if your data base design allows you to build a workable form/subform, it should also support a query which gathers the same data. Use that query as the record source for the report. And use the report's sorting and grouping features to create the quote grand total.
Edit: With the main form/ subform approach, each new row in the subform should "inherit" the quote_id value of the current record in the main form. You ensure that happens by setting the link master/child properties to quote_id. Crystal Long explains that in more detail in chapter 5 of Access Basics by Crystal: PDF file. Scroll down to the heading Creating a Main Form and Subform on page 24.
Edit2: Your strategy may include storing Products.ListPrice in QuoteDetails.ListPrice. That would be useful to record the current ListPrice offered for a quote. If so, you can fetch ListPrice from Products and store it in QuoteDetails when you select the ProductID for a row in the subform. You can do that with VBA code in the after update event of the control which is bound to the ProductID field. So if that control is a combo box named cboProductID and the subform control bound to the QuoteDetails ListPrice field is a text box named txtListPrice, use code like this for cboProductID after update:
Me.txtListPrice = DLookup("ListPrice", "Products", "ProductID = " _
& Me.cboProductID)
That suggestion assumes the Products and QuoteDetails tables both include a ProductID field and its data type is numeric. And cboProductID has ProductID as its bound field and uses a query as its RowSource similar to this:
SELECT ProductID, ProductName
FROM Products
ORDER BY ProductName;
