Problem solved thanks to Karen Z., Linda G., Fred R., Lin S., and Shelley S.!
I had overlooked the right-click on the TOC. I thought the Format > Document > PDF Setup > Bookmarks tab was supposed to do the trick. Now I will remember: 1. Open .book and mark TOC as selected. 2. Right-click and select Set Up Table of Contents or Edit > Set Up Table of Contents 3. Move desired format to the Include Paragraphs Tagged box. Thanks everyone. regards, Karen Mardahl > -----Original Message----- > Frame 7.1p116, WinXP > I have a TOC with only 3 headings. > I added a Heading 4 to the other files in the .book.
