Field changes value

I have a text field that uses a value list with a popup. The field is formated as a combobox.

This field keeps changing to the second value in the list. Sometimes it will not let me choose another value. I have tried it both as editabe and non-editable.

Other similiar fields on this form seem to be working normal.

Just a thought:

Do you have an if statement containing a
“=” (assignment) instead of a “==” (comparison) in one of your methods?

Would produce these symptoms.

It was in a calculation. Thank you for the suggestion.
