VB.Net / Crystal Report 2008

[kerv21]

I am having trouble passing in an integer as a parameter to my report.
Here's the code that is being executed from a click event of pushbutton:

Dim fp As New frmPreview
fp.CrystalReportViewer1.ReportSource = txtLabelFmt.Text                
fp.CrystalReportViewer1.ParameterFieldInfo(0).CurrentValues.AddValue(Val(tvNewOrders.SelectedNode.Tag))
          
fp.CrystalReportViewer1.Refresh()
fp.ShowDialog()

Any suggestions ?
