Dawa,

>... Howerver, when I pressed the buttons that calls DOREPORT.PRG and DOLABEL.PRG, I couldn't get any result.

Maybe this sounds stupid but both programs sound very close
to reserved words. Did You try something idiotic like renaming
them to DoMyReport.prg and DoMyLabel.prg? or even give them
total different names.

And they are included in the project-Manager are they?
(sorry if this question sounds rediculous)
