problems passing parameters

I am using Crystal Reports 10 and Visual Studio 2005 (vb.net). I have created a report and need to pass it parameters. Below is the code I am using. On the line ParamField = ParamFields("Department"), I am getting the error System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values.

If I don't try and sent parameters the report load fine. Does anyone know what could cause this?

Dim ParamValue As New ParameterDiscreteValue
Dim ParamFields As CrystalDecisions.Shared.ParameterFields
Dim ParamField As CrystalDecisions.Shared.ParameterField


ParamFields = CrystalReportViewer1.ParameterFieldInfo
ParamField = ParamFields("Department")

ParamValue.Value = hospital.SelectedValue
ParamField.CurrentValues.Add(ParamValue)

Have you created the parameter ("Department")in the crystal report in the design time?

There is a parameter named Department in the report. What do you mean by "in the design time"?

Just do one experiment , dont pass it as a parameter , just directly pass it into a formula field and see what its passing , may be u can find some mistake in it.

I meant when you designing the report.
Anyway if the department is added to your report as a parameter field there must be some other problem.
