Hi,

I have a distinct list of state-county parameter and a text box that displays this value if selected.

How do I create an expression that is (Select all) is selected then display 'All' rather than every state-county name being displayed.

=IIf(IsNothing(Parameters!pStateCounty.Value), "All", Parameters!pStateCounty.Value)

this expression is not working since a multivalue parameter cannot be set to null and I get an (error)

Thank you.

The only thing I think you can do is compare the number of selected items to the total number of items.
iif(Parameters!pStateCounty.Count = Count(Fields!StateCounty.Value, "MyStateCountyDataSetName"),"All", Join(Parameters!pStateCounty.Label, ",")

Thank you for your response. I used your expression with 'countdistinct' and it worked great.
