Here is the Relations Model (colored dots show the appropriate relation):
My goal is to create a Form or (Form + SubForm)- where user will add data as following -
User will select the EmployeeName, and then - will proceed with the Category selection.
Then - will enter the Objective values (Yes, No or N/A) according to each Category associated with its Objective.
I created the Main Form (data source - ChartReview table):
and the Sub Form (data source - dimensions - Category, Objective tables):
But - my problem - I don't know how to connect MainForm + SubForm...
(so the user would enter data into Main, and then would be transferred to a Sub and will enter Yes/No/N/A for each Objective)
Also, I need my Yes/No/N/A values would be bound to each Objective, while now, unfortunately they're bound to only the 1st Objective...
And the last, I am not even sure the user will actually be able to fill out my SubForm, as it's created out of the Dimensions.
When I tried to enter or to change the info in the SubForm - the following error appears:
Any advice or suggestions - welcome !!!

Answer 1

Open the form in design view.
Click on the subform to select it.
If you can't see the properties pane, Right click on the subform and choose properties.
On the data tab there are the fields that you need to fill in.
Link Master Fields and Link Child Fields.
To start, put 3_Employee.ID in the "link Master fields" box
and ChartReview.EmployeeFK in the "Link Child Fields" box.
Manually enter valid data to test that the employee record works, then add the other links once this works.
