Thanks for the reply, Borislav.

In other command button,some programmers used

thisform.oAP.GetHighestInvoiceLine(v_APInvoice1.APInvoiceId) + 1

that line works fine. GetHighestInvoiceline is anothe function which is available in cap.prg.

and I searched main.prg for
set procedure to cap.prg

that is not available in main.prg.
