Hi Bruce:
Yes, now that it's working, I'm not going to change it.;-)
By the way, I recreated this report using the Sales Order Detail table (We had to exclude miscellaneous charges - and those are not in the header table). I used pretty much the same formula ('Amt' instead of 'Total Dollar Value') - and everything worked like a charm. And the user I wrote this for seems to like the result.:-)
Thanks all for your help!
Andre
