Selection Frames
You can format the fields by putting them in a selection frame.
You can specify the Screen Title text by double clicking the TEXT-001 (Can also be TEXT-002,TEXT-003..etc). This will navigate you to a screen to specify the text for given title. Make sure to save and activate before you navigate back to the program or it will not work.
