How to use two different report items in SSRS page header

Hi All,

Can we use more than one report item in SSRS 2008 R2 page header...

Like this in expression..

=IIF(Globals!PageNumber=1,ReportItems!Col1.Value,ReportItems!Col2.Value)

Whenever Globals!PageNumber=1 I want to show values present in Col1 and when Globals!PageNumber<>1 then show values present in col2

Also let know if any other work around is there to meet above criteria...

Thanks,
RH
