Removing all occurrences of "From Dual" allows this to work in SQL Server 2008 with no problem so thank you very much for posting nearly readily consumable date.

The thing that I'm confused about is that you say you want it to show "Sub Total" but I only see "Grand Total" in the code.

If you want help on this, I'll need a bit more information. Thanks.
