Dear Jim
It would be helpful if you could post what your selection formula is, as well as a more detailed description of what information you have entered in the detail area of your "invoice" and what date range you wish to print so we can help you more accurately.
One suggestion would be for example, to use a selection critera of:
{InvoiceDate} in MonthToDate
If you wish to see just current month's invoices. Be aware however, that if this is the criteria you want, but you wish to print December's invoices, you will have to change the "print date" in QRWIN to reflect a date of December 31, 2000, rather than the current date of January 15, 2001. To do this, go to the Report menu Option and select "SetPrintDate" to modify the date you wish to print for.
If you are getting one detail line per page, check the format of the Detail section by going to the Design window, right clicking on the left-section title "Details", then selecting Format Section. Make sure you do NOT have the option "New Page After" selected.
If this does not help, please submit more detailed information as requested.
Regards
