Table of Contents
On submitting my file, I have recieved a message saying that there do not appear to be any chapters in my Table of Contents and suggesting that I need to set chapter divisions.
I had already used Heading 1 for title and section headings and Heading 2 for chapter numbers. Is there something else that I need to do? I can find no further clues in the guide.
