I have a VB.Net running a Crystal Report 11 report. This report takes 2 parameters. I have this already set up in my app and in the report. However, I keep getting prompted to enter parameters. How do I get rid of these prompts? Also, I get the below error when I set both of these parameter values to NULL. Here is my code below:

Code:
    Public Function AccessGASR(ByVal strUserID As String, _
                               ByVal intGroupID As Integer, _
                               ByVal strInputType As String, _
                               ByVal strReportPath As String)
        Try
            rptErr.clsModule = "GroupActivitySummaryReportDLL"

            Dim crDoc As New rptGroupActivitySummary

            With crConnectionInfo
                .ServerName = "HERCULES"
                .DatabaseName = "Drip"
                .UserID = "CRVBNETSQL"
                .Password = "SC1800fuels"
                .IntegratedSecurity = True
            End With

            crDoc.SetParameterValue("@userID", strUserID)
            crDoc.SetParameterValue("@groupID", intGroupID)

            If strInputType = "O" Then
                PrintGASR(crDoc)
            ElseIf strInputType = "B" Then
                CreatePDFReport(crDoc)
            End If

        Catch ex As Exception
            rptErr.clsProcedure = "AccessGASR()"
            rptErr.clsMsg = ex.Message
            rptErr.WriteToTextFile(ErrorDirectory, "DRIP-ErrorLog.txt")
        End Try
    End Function
Thanks,
