SSRS 2005 - Running Group Count

Question

How do you you display the running GROUP count via SSRS 2005?

I have a report that has n groups where the source data must remain anonymous and I want that number in the header of the group...

So instead of the name in the group header like such...
Employee - John Smith
Employee - Mary Swain
...
Employee - Ahmad Sal

I want...
Employee #1
Employee #2
...
Employee #n

Thanks!!!

Answer 1

=RunningValue(Fields!Employee.Value, CountDistinct, Nothing)

Voila!

Answer 2

Use

RowNumber("table1_Group1")
