Thanks, I have created the sql manually and although not an experienced user of
sql think I am on the right track.
The UI displays exactly want I want by using a number of grids to display the
child tables of allergies and medications; that was no effort at all given how
user friendly dabo is. Trying to produce a report containing that same
information is what has me confused right now. I am sure there is a simple
solution which I cannot see yet.
