VB.Net / Crystal Report 2008

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:

Code:

---

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 ?

Try this:

Code:

---

ReportName.SetParameterValue(parametername, variable)

---
