Dynamic Grouping Group Header Problem

Hi, I am currently trying to create a report the dynamicaly groups from parameters. The grouping part works fine but I need to show the parameter label name or the field referenced by a parameter.

=iif(Parameters!Param1.Value="P",Parameters!Param2.Label,Fields(Parameters!Param1.Value).Value)

This is the expression I have written to do this. The problem seems to be is with the true part of the iif statement. The false displays fine in the group header. The Parameters!Param2.Label also displays if used on its own.

This is the error that is fires back when I run the report.

The Value expression for the textbox ‘textbox4’ contains an error: The expression referenced a non-existing field in the fields collection.

I am quite new to SSRS and I am using VS2005 pro.

Thanks

D,

Try

iif(Parameters!Param1.Value="P",Fields(Parameters!Param2.Label).Value,Fields(Parameters!Param1.Value).Value)

I believe this should work for you.
