[Forums] how to populate combobox items inside table records

Good to hear. The combo box is bound to the column in the underlying record that is being updated. The source of the combo box in my case is simply an entity. Your example stated the values needed to be ones not selected. I would suggest creating an action that queries data to determine the "not selected" answer set that executes On Change or any change to refresh the list. This may get tricky with it executing very frequently and trigger from several events.
