Data element names aren’t always obvious when looking at an interview, especially when you have the Caption command, or when using ChooseFromDataSource, or ChooseFromFile. And of course, it is crucial for you to know the data element names when troubleshooting templates.
And so the way to find out what the data element name of any control on the interview is, is as follows:
1. Click on the menu in the top right corner of the interview
2. Click on “Advanced”
3. Click “Show Hidden Fields”
4. Hover over any field to reveal its data element name
