I have a report that has as the main group a "Location" at the location there are "Switches" on which there are "Keys" and connect to the Keys are Fittings. What I want is to show each of the controls only once but with a summary of the fittings for each switch and each Key. If I do not create groups I can control the the duplicates by checking the is visible property of the preceding heading. e.g. for the switch control iif(Location.isvisible,Switch,Null) etc, however as soon as I set up grouping unless I put each control in its own heading I cannot surpress duplicates. Any suggestions greatly appreciated .
