Team,
I tried some resolution on this forum regarding this issue and i cannot find any solution on my case.
The issue i had is how to filter a SharePoint choice column in PowerApps
So i have this SharePoint list table (tblProgram). the Program column is a choice type.

I need to do is when region is selected the program field will only show /filter the data based on the SharePoint data value above.
the Program field below is a combo box in Power Apps. In the example below. i dont need to see the 5G on the displayed value in the Programs because Augusta GA has no 5G program. only DES and MA
Code for Select Region field
ForAll(Distinct(tblFSLClosure, Region), {Result: ThisRecord.Value})

any idea on how i can do this?
