"Auto-fill" can mean more than one thing to different people. Are you trying to copy data from the related tables into corresponding fields in the layout's table or are you just trying to bring up the data from the related tables on your layout?
Either method relies on a working relationship to match the current record on your layout to a record in one or more related tables (or table occurrences).
See this thread for a description of both methods and how to set them up: Auto Fill
i think that (trying to bring up the data from the related tables on your layout) is what im looking for, as i showed in the FM starter examples thats what they do, so if ANYONE has ANYTHING to help, that would be great... i will pay for support...
