I'm having trouble using a calculation based on a field value to select the active segment in a button bar.
Let's say I have a three-segment button bar, with segments labeled "One" and "Two" and "Three", and a field with a value that will be one of "One" or "Two" or "Three".
If I set the selected segment to a calculation based on that field value, nothing changes as I move between records.
What am I missing? How do I get a button bar to activate a button that matches a field value?
I am attaching a demo file that matches my goal setup and demonstrates the behavior.
