Ok, I've played around with this, and it doesn't quite work the way I need it to, and if I understand things properly, I don't think I can get it to do what I need.

The problem is that the content that I am referencing is the start of the second section, but it is a continuous section break. So placing the SECTIONPAGES field in the first section, if the section break falls at the beginning of page 4, I get one result (3 pages for the first section) but if it starts in the middle of page 4, I get another result (4 pages for the first section).

What I really need to know is what page the NEXT section starts on, not how many pages are in the first section, but I don't see a way to do that other than using a PAGEREF to the bookmarked content, which you indicated doesn't work with a mail merge.

Am I missing something, or is this beyond the capabilities within a mail merge?
