[Brian Henry]

I'm trying to add a text field to my report and i get an error.

Error = Invalid Field Name

The name of my textbox = AVGCFS1

Heres My Code

Public SelectDate As String
    Dim Report As New CrystalReport1 'your report document
 
    Private Sub Form2_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Try
            Dim pval As New ParameterValues
            Dim disVal As New ParameterDiscreteValue
            disVal.Value = "abc"     'Set the discrete Value
            pval.Add(disVal) 'add the parameterdiscretevalue to the collection of parametervalues
            Report.DataDefinition.ParameterFields("AVGCFS1").ApplyCurrentValues(pval) 'add the parameter to your report document
 
            If SelectDate = "" Then
                CrystalReportViewer1.ReportSource = Report
            Else
                CrystalReportViewer1.SelectionFormula = "{IntakeData.DateStamp}=" & "'" & SelectDate & "'"
                CrystalReportViewer1.ReportSource = Report
            End If
        Catch ex As Exception
            MessageBox.Show(ex.Message, _
               "Error.", _
               MessageBoxButtons.OK, _
               MessageBoxIcon.Error)
        End Try
    End Sub
