When we put Invoice Date into the detail section and printed, all of the dates showed Dec 1/2000, thus the reason those records were selected. The selection formula was working correctly. Should the invoice date for some of those transactions be different than Dec 1/2000, then there is a different issue.
The DBit Recurring Billing table being used was one written for QR DOS. Because it is a single level table, QRWin should be able to read it OK. However, linking does work differently between the 2 versions of Quik Reports, so if the links were causing the invoice date to appear incorrect, that may be a table issue.
Verify in Recurring Billing what you expect the invoice dates should be, then you can determine what should be printing in Quik Reports for Windows. The best way to test this is to only select fields from the CHGH - Invoice Header file, so that there are no linking issues that could change what prints. Put all fields into the detail section.
