Input data into a table using DLookUp in Access - forms

I am using a Data entry continuous form to input data into a table named 'Order_History'. All fields successfully input their data into that table except for one. I have a text box that uses DLookUp to get the value from a combo box on that form and use it to select data in hopes of entering it into the table. The DLookUp is getting the data from a different table named 'Postcodes'. I assume that the reason the others work is because the control source is linked to columns in the table.
Is there a way I can link this text box (Drop_Number) to the specific column in my Order_History table while still using DLookUp to get the values?
My DLookUp code:
=DLookup("Drop_Number", "Postcodes", "Postcode = [Forms]![Order_Form]![Postcode_cb]")

Update a table via a Form with Data from Inputs on the Form and from another table

being new to coding I have run into a wall. I am attempting to update a table "Data_Tbl" from a Form "Form1" with inputs, and a value from a second table "Temp_Tbl" (Which contains predetermined temperature data) based on a Temperature keyed into a field on the Form. My "Temp_Tbl" has 2 fields "Temp" and "TDS" while the "Data_Tbl" has 3 fields to gather data from the form and "Temp_Tbl", "Serial", "Temp" and "TDS". I would like to populate the "TDS in the "Data_Tbl" from the "Temp_Tbl" based on the "Temp" keyed into the "Form1" and send it to the table "Data_Tbl" I have attempted to use the answers put forth in this site but to no avail. All I get are errors with the code. I am slightly familiar with VBA. Any help would be appreciated. I have tried so many things, I don't know what to put as an example.

Create a dynamic table in a PDF Form programmatically

I need to generate a pdf based on a template form.
In that form there is a table that needs to be populated.
Since the table can have a unknown amount of rows, what I was thinking was drawing the table and then adding it to a space on the form.
As in, the form would have a acrofield to receive the table itself.
I already managed to create the table and put it inside a pdf, but I'm having issues puting that table into a acrofield.
As far as I can understand a form only appears to accept these: button, text, choice, or signature.
I'm using Apache pdfbox and easyTable to manipulate the form and create the table.
Is it possible what I want to do? If so, where can I find more information about this topic?
Edit: This answer seems to be what I want to do.

How to store DLookup from [Form] to Table Field in MsAccess 2013?

I have two MS Access tables: IdMhs and T_UKT. I want to automatically fill in [IdMhs].[SPP] from some criteria in [T_UKT].[UKT]. I cannot put it in query relationship, because the row cannot be edited on a form.
So I make a form and I get the number SPP (a textbox on form) automatically by using and it works fine:
=DLookUp("SPP";"T_UKT";"UKT = " & [Form].[UKT])
The problem is: the lookup value just shows on the form, and the results are not filled in the field in table ([IdMhs].[SPP]).
Any idea what an expression I should write to fill it in IdMhs table automatically?
Need macro or VBA code to save value into table. If form is bound to IdMhs table, simply like:
Me!SPP = Me.tbxSPP
The real trick is figuring out what event to put the code into. You have a control (possibly combobox) where the UKT value is selected? Use its AfterUpdate event.
Why do you need to save the SPP value and not just retrieve it in a query that joins tables?
What is nature of table relationship? Is T_UKT a lookup table? If so should be able to include it in form RecordSource and then the SPP value would be available for display in textbox and DLookup not needed. Domain aggregate functions can perform slowly on forms and reports and should be a last resort option. The same code would be used to save the value. The query join should be 'show all records from IdMhs and only those from T_UKT that match'. Set textbox bound to T_UKT SPP field as Locked Yes, TabStop No.

Cannot see records in form bounded to table in Access

I have a form and it's record source is a table. I created the form separately and added the control sources to the different fields in the form and also changed it's record source. I imported values from an excel sheet into the table and when I open the form, I do not see the tabe values being displayed in the form. Any idea what I should do to see the table records in the form?
In form design mode, check the form's DataEntry property. It sounds like yours is set to Yes, which hides existing records and only allows new entries. Change it to No and you will see the existing records.
Another possibility is that a filter is active and no records match that filter.
Use a form wizard to generate a working form based on your table. Then once you can see the data being displayed in the form, customise as needed.

Invisible value when creating new record

I have problem with some form in Access 2010. In one of the fields (Amount) I have as a value expression =IIf([IsNull([Code]);1;2) . In the form the values 1 and 2 are shown correctly but when I try to save the newly created record I have an error: You have to fill the Amount field. Can someone tell me why the value is not visible when saving new record to database?
You need to use VBA code on the NewRecord and/or BeforeUpdate event to insert these values into this field/textbox. What you are doing here amounts to setting a value for Display only.
