I read through the tutorials that I have found here regarding InScope but I was trying to get the "full" definition of what it can be used for.  Unfortunately even the MSDN page is pretty much useless.  The one I found is:http://msdn.microsoft.com/en-us/library/ms156490(SQL.90).aspxIt is maddening that this is all Microsoft uses to describe.Is there a better description of using InScope?  I have tried the example from another blog:=Iif(InScope("matrix1_ColumnGroup1"), Iif(InScope("matrix1_RowGroup1"),                                 "In Cell",                                 "In Subtotal of RowGroup1"),             Iif(InScope("matrix1_RowGroup1"),                                 "In Subtotal of ColumnGroup1",                                 "In Subtotal of entire matrix"))I am just trying to understand how (and why) it works for both Totals/Sub-Totals but also as the MSDN example of calling another report.John
