It works. Just as I needed. Many thanks.
John: That suggestion didn’t work the way I wanted it to, but thanks for the idea.

I think I can do this by collapsing the data but is it possible to do this while retaining the data set in its 'original' state. I have searched the archives and the reference manuals but have not come up with anything that seems to be what I want.
