So, I looked at the StyleRef link but could not understand how to follow instructions that applied to a book layout - chapter titles on left (even) page and page numbers on odd page. I am able to set up the odd/even format, but didn't see how the StyleRef would allow insertion of the chapter titles on the even pages. From other web instructions, they said to [Insert] [Cross Reference] [Heading] which worked for most of the pages, except where it failed. Any suggestions on how to set up chapter titles in the header of an odd/even typical book layout using StyleRef?
