Error: Column ''ProductID'' does not belong to table Table"

Hei Clay, Here is the sample you''ve asked for yesterday. After you Extract, please read the ReadMe.txt file to see what I am trying to do. Thank you in advance for your help. Test_8831.zip

What version of our products are you using? I tried your sample with both the 2021 beta and the 1.6.1.8 version, and did not see the problem. I typed 10 into the combobox, clicked on the empty cell under ProductID, typed 1, and then tabbed to next cell without seeing any problem. Should I be doing something else?

I am using an old version: 1.5.2.0 I will download the latest version and use that. Thank you !

Hei Clay, Do it this way: Select first a Category and some products will be displayed. Then type in Category 10, no products will be displayed (grid will clear out) and now we type in ProductID 1 and tab out. This is when the error occur.

With those steps, I still dont see the problem in 1618 or 2021. Do you?
