Go To Page button to link to document within a Book?
I bet the answer to this question is very simple, but here goes...
I'm working with a Book, made up of four InDesign documents. On one of the documents I'm creating Go To Page buttons that I want to link to various pages within the book - however, it seems I can only add page numbers with that particular InDesign doc, as appose to any of the four docs within the book.
Is there a 'include pages from book' option somewhere? Or another way to letting me link the button to another page within the book?
Thanks,
