I added a 2nd Subreport to my Crystal Reports and after that I get this error, When I remove the 2nd Subreport it works fine.

I use below code to set datasources for the subreports.

CreateFeePaidXML()

and

CreateAdditionalFeeXML()

both are functions which return datasets.

This is the formula, which works fine before I add the 2nd subreport.

IIF ({PaidFee.paidamount} = 0,'' ,TOText({PaidFee.paiddate},"dd-MMM-yyyy") )

What I have tried:

VB

frmRptViewer.CrystalReportViewer1.ReportSource = rpt
                       rpt.Subreports(0).DataSourceConnections.Clear()
                       rpt.Subreports(0).SetDataSource(CreateFeePaidXML())
                       rpt.Subreports(1).DataSourceConnections.Clear()
                       rpt.Subreports(1).SetDataSource(CreateAdditionalFeeXML())
                       frmRptViewer.ShowDialog()

When I removed the Formula field from the other subreport (which was giving error), now after that the subreport(1) show blank report.

Resolved the problem, swapped subreports indexes fixed the problem
rpt.Subreports(1).SetDataSource(CreateFeePaidXML())
rpt.Subreports(0).SetDataSource(CreateAdditionalFeeXML())

but still I thought the report I added first will have o index and the later will have 1 but its not.

I still dont know how to check subreports indexes.
