** This sould be cause by your programming error. Do you have any grid in your Purchase screen, and setting the wrong control source for the column?

>(I'll clean them all, of course, I'm just trying to understand if there's any logic in what I'm doing...usually there isn't...he he he)

** Since I include the report file in my EXE, I need to clear the TAG & TAG2, EXPR so that the SET PRINTER command can work for others printer in my EXE, else the report will fixed to the printer during the report designed.
