• Thank you. For the most part it worked except that I am not able to group by client ID. I can group by staff and program. Below is the Iif expression. Where am I going wrong.

    =iif(

    Parameters!GROUPING.Value = "Staff", Fields!UserCode.Value

    , iif(

    Parameters!GROUPING.Value = "Client ID", Fields!ClientID.Value

    , Fields!ProgramName.Value

    )

    )
