So I switched the formatting of my page numbers to be per Chapter, (e.g. Page 1.2, 3.40, A.3) per Heading styles. In the TOC document, when I build the TOC, each chapter is displayed correctly, but all of the pages are the first number in the chapter document (e.g. Page 1.1, 3.1, A.1) for all headings and subheadings.

I've been wrestling with this for a while but can't figure out how to get the pages to increment off of the first page of each chapter.
