CR parameter problems in asp.net - losing hair!!!

Hi folks.. I'm an classic ASP dinosaur trying to get started with ASP.net and the following problem has me stumped.

I've got a very basic crystal report bound to an s_proc that takes 5 parameters.. I keep getting "input string was not in correct format" when I try to pass the parametervalues to the report document.

Thanks in advance!!!


Dim oRpt As New ReportDocument
Dim conn As New SqlClient.SqlConnection

oRpt.Load("c:\dev\dotnet\" & aReport)

Dim param_values as New ParameterValues

Dim param_prot as New ParameterDiscreteValue
Dim param_rpn as New ParameterDiscreteValue
Dim param_cra as New ParameterDiscreteValue
Dim param_startdate as New ParameterDiscreteValue
Dim param_enddate as New ParameterDiscreteValue
Dim param_option as New ParameterDiscreteValue


param_prot.value = fldparam3.text
param_rpn.value = fldparam2.text
param_cra.value = fldparam4.text
param_startdate.value = fldparam5.text
param_enddate.value = fldparam6.text
param_option.value = Int32.Parse(fldparam1.text)


param_values.Add(param_option)
param_values.Add(param_rpn)
param_values.Add(param_prot)
param_values.Add(param_cra)
param_values.Add(param_startdate)
param_values.Add(param_enddate)

oRpt.DataDefinition.ParameterFields("@Option").ApplyCurrentValues(param_values)
oRpt.DataDefinition.ParameterFields("@RPN").ApplyCurrentValues(param_values)
oRpt.DataDefinition.ParameterFields("@ProtNo").ApplyCurrentValues(param_values)
oRpt.DataDefinition.ParameterFields("@CRA").ApplyCurrentValues(param_values)
oRpt.DataDefinition.ParameterFields("@StartDate").ApplyCurrentValues(param_values)
oRpt.DataDefinition.ParameterFields("@EndDate").ApplyCurrentValues(param_values)


it dies on
oRpt.DataDefinition.ParameterFields("@Option").ApplyCurrentValues(param_values)

when I'm trying to pass my first parameter.. @Option is defined in my sproc as an int.



output from the dot.net debugger is as follows
