Problem with printing multiple copies of a report

[Jeff]

I read and follow the suggestion from this group to wrtie the code for a
print sub:

DoCmd.RunCommand acCmdSaveRecord
DoCmd.SelectObject acReport, "rptCertificate", True
DoCmd.PrintOut acPrintAll, , , , InputBox("Enter Number of Copies", _
"Print repCertificate", 1), 0

Access prints one copy even I put 2 in the InputBox or use
DoCmd.PrintOut acPrintAll, , , , 2, 0 in stead.

Thank you in advance for your help.
