Hi ahblake,
I wanted to follow up and share. my form is now working perfectly after following your advice.
I was attempting to use the ${savedClasse} in the default column, which wasn't behaving as expected.
I moved the calculation from the default column to the calculate column, added a trigger (as in your file). the form now correctly pulls the ${saved_value} and my multiple-choice list is now loading stored values. This was the missing piece of the puzzle.
Thank you for the guidance!
