I wasn't able to make my document give me totals correctly (kept getting a calculation error that would continue through my (small) recordset) - so I started again with your attachment and gradually introduced my own field names and structure and that worked like a charm. Thanks!

But, I don't have much confidence that I can make changes w/o 'breaking' it. For example, what determines when one needs to wrap code with double quotes? Is there any documentation you could refer me to so I can understand the syntax better? I assume that the opening and closing braces
have to be paired, but with nesting it quickly becomes difficult to tell if you're missing a brace. Any thoughts?

Thanks again for your help.
