I've attached the last database you posted and just added the tblColors to it. I couldn't get a screenshot of what I'm trying to describe so I'm going to explain it the best I can. Here's what I'm looking for...
Select Product A from the ProductName combobox.
The TestNames that appear in the subform are Color, Density, and pH.
I want the TestResult field for Color to be a combobox which displays a text value but stores the number in tblResults. Then density and pH are left as is to enter numerical values.
For example, let's QC Product A again...
Lot number is 1111
I want the user to be able to pick from a list of colors (Brown, Blue, Green, Yellow) from a TestResult combobox next to the Color TestName. Let's say they picked Green.
Then enter a numerical value for density (1.020) and pH (7.50).
The records stored in tblResults should be:
ProductName - LotNo - TestName - TestResult
Product A - 1111 - Color - 3
Product A - 1111 - Density - 1.020
Product A - 1111 - pH - 7.50
Let me know if that makes sense!
