Hi I am trying to get a textbox in report header to display "All" when user selects "Select all" for parameter value rather than have all the values displayed in comma delimited list but so far nothing gets displayed in the header textbox and no error messages?
I have a textbox in report header with this expression
=ReportItems!textbox23.Value
In hidden textbox23 in report body with this expression
=iif( CountRows("Rcelist") = Parameters!RceCode.Count, "All", Join(Parameters!RceCode.Label, ", "))
