I am having problems bringing my Crystal Reports over
to .NET.  Simple reports work fine, it is when I try to
use my reports with subreports I encounter some parameter
problem with the sub-report link.  The exact same report
works OK in VB6, so I guess my new .NET syntax is wrong
somewhere.

Any ideas??

The error message I get is:

"Error in file K\:Reports\ProductSummary.rpt:
Error in formula <Simplified Sub-Report Record Selection>
({ContractSummary_ttx.NPC} = {?Pm-ProductSummaryAll_ttx.NPC})
This field name is not known"

The code I am using is:

Dim crReport As ReportDocument
Dim crSubReport As ReportDocument

        crReport = New ReportDocument()
        crReport.Load("K:\Reports\ProductSummary.rpt")

        'set reports datasource
                crReport.SetDataSource(dsReport.Tables("PRODUCT"))

        'set subreport
        crSubReport = crReport.OpenSubreport("ContractLines.rpt")

      'set subreport datasource
                crSubReport.SetDataSource(dsReport.Tables("CONTRACT"))

        'send the report to the viewer
        crViewer.ReportSource = crReport
