Some headings (1, 2 or 3) are missing in my table of contents. It seems to be on specific pages. On a page that is working properly, I can add multiple headings and they all work. On another page, no headings work. I copied a working heading to a non-working page and it did not work. I have deleted and added the table of contents several times. Any ideas?

Thanks, Jim

Are your non-functional headings by chance inside a table or text box?

Thanks Charles, very worthwhile reading. I learned about manually marking the text (Alt+Shift+O) and that solved the problem.

Best wishes,
