What method are you using to launch the report? Here is some code for the ActiveX component:

with Report
.ReportFileName = App.Path & "\Report1.rpt"
.ParameterFields(0) = "Shift;" & intShift & ";TRUE"
.ParameterFields(1) = "Unit;" & gintUnit & ";TRUE"

End With

intResult = crptOrderPad.PrintReport

Fool around and see if you get used to it.
