[reporting-services] Display Parameter(Multi-value) in Report

I didn't know about the join function - Nice! I had written a function that I placed in the code section (report properties->code tab:

Public Function ShowParmValues(ByVal parm as Parameter) as string
   Dim s as String 

      For i as integer = 0 to parm.Count-1
         s &= CStr(parm.value(i)) & IIF( i < parm.Count-1, ", ","")
      Next
  Return s
End Function
