Yes, I'm using multiple detail bands in VFP9 report,each band for each table.I have added the expression in "print when" to check the selection by user, and it's working fine where all the selected data is in the report, but I found that the somehow the VFP will allocate some space for the detail band even there is no data. As an example, my 1st page of the report is showing all the default table(user can't do any selecion), and the 2nd page is all the optional table(user selection). When there is no optional table selected, the 2nd will show a blank page instead of 2nd record. Please advise, thanks.
