I put a subreport(weekly summary) in report footer and link the parameter in subreport to same parameter (eg. area, network)in primary report (daily summary); but when primary report's parameter changes the subreport data doesn't change. I think it's because the subreport is in the report footer section not the detail section or group footer/header section. If I put it in the detail or group section it works ok but I can't put it there because I already have different groups in primary report and if I do so the subreport would show under each line of group of the primary report which is not what the user wants. They want to see all the groups together for daily summary and for weekly summary. I think maybe some kind of programming is needed in Crystal to get this work? We use Crystal 8.5. Thanks a million!
