Hi, Susan,
Actually, it sounds like you were about 80% there... Bookmark and cross-reference will get you there, you just have to select the reference as a page number rather than the Bookmark Text.
This article (
How to update a page number reference in a Word document | TechRepublic) gives a pretty good walk-through with some images. When you have your relevant spot bookmarked, where you want to insert your cross reference (Insert/Cross Reference), you'll select Reference Type as Bookmark and on the upper right, Insert Reference to: change that to Page number. You may have to update that if/when it moves to a different page, but if you print or print preview, those links should update.
Best of luck,
Ann
