Disabling a button with (somewhat) tricky criteria

I want to disable a button in a table if two columns in that table (formatted as text) exactly match two other columns in a different table (row specific)

Hopefully that makes sense. Screenshots explain more.

Hi @Scott_Weir,

Does this do what you want? I’ll admit that it was a bit hard to understand the structure of the tables you were describing.

==> Disable If: [Master Feedback].Filter(Student=Student AND Teacher=Teacher).Count()>0
