'Value' is not a member of 'System Array'?????

[ssfftt]

i got sample code for crystal report, here is the part of it:

' Objects used to set the parameters in the report
Dim pvCollection As New CrystalDecisions.Shared.ParameterValues()
Dim pdvCustomerName As New CrystalDecisions.Shared.ParameterDiscreteValue()
 
' Set the discreet value to the customers name.
pdvCustomerName.Value = cbCustomers.Text
 
' Add it to the parameter collection.
pvCollection.Add(pdvCustomerName)
 
' Apply the current parameter values.
rptCustomersOrders.DataDefinition.ParameterFields("@CustomerName").ApplyCurrentValues(pvCollection)

I am learning and put almost exactly the same code in my project:

Dim CrystalReportCurResult As New CrystalReportCurResult
Dim pvCollection As New CrystalDecisions.Shared.ParameterValues
Dim pdvRID As CrystalDecisions.Shared.ParameterDiscreteValue()
pdvRID.Value = ModuleUser.curResultID
pvCollection.Add(pdvRID)
CrystalReportCurResult.DataDefinition.ParameterFields("@CustomerName").ApplyCurrentValues(pvCollection)

But on the third line of my code, the "pdvRID.Value" seems having problem, VB.NET gives message "'Value' is not a member of 'System Array'". Why is that? it works fine in the sample code, whats wrong is it here? plz help
