asp classic passing multiple Parameters

[LooseUnit]

Hi,

Using Crystal 11 & Classic ASP.
I am trying to pass multiple values for my second parameter to my crystal report.
have becom a little stuck as there is little on goolge to assist.
Current code:

If Request.Form("CMU")="" Then
session("oRpt").ParameterFields(1).AddCurrentValue(0)
'SelectionText = SelectionText & "No Tax"
Else
session("oRpt").ParameterFields(1).AddCurrentValue(Cint(Request.Form("CMU")))
End If

session("oRpt").ParameterFields(2).EnableMultipleValues = True
session("oRpt").ParameterFields(2).AddCurrentValue(Cstr(Request.Form("Cable")))
'Read database records into report in separate step
session("oRpt").ReadRecords

This works fine for single values (usually without the EnableMultipleValues)

Any help on where to go from here would be appriciated.

Thanks
