Call Crystal Report from Flex with parameter

[ddozer]

I found some info on the portal about calling a custom crystal from flex in ES and I have been able to get a test report to work, but I want to pass a parameter value to the report automatically without having to prompt the user. here is my code for calling the report from a button added to the voucher entry screen:

Private Sub OrderData_Click()
Shell "c:\program files\exact software\bin\reportspawner.exe -r" & Chr(34) & _
"PROAMSQL" & Chr(34) & " -D" & Chr(34) & "411" & Chr(34) & _
" -u -T6 -~ -N" & Chr(34) & "PO_Report_Test" & Chr(34)
End Sub

I'd like to be able to pass in the value that the user enters in the PO number field then have them hit the button to run the report. Does anyone know the syntax to accomplish this?

Thanks,
Dave
