I have a problem with multiple drill down.  I have Report1 with a Sub Report in the Group Footer with Hide(Drill Down OK) set. When double-clicking a row the drill down works fine.  Within the Sub Report is another Sub Report with the same settings.  However on Double clicking a row in the sub report down does not result in drilling down again.  However, when opening the sub report and double clicking the drill down works fine.  Is there a limit or could someone give me a clue as to what might be going on

You are correct.  Can't have a subreport within a subreport.
