First please don't cross post. Anyone searching later will
find the same question and think it was unanswered. Please go to
the other thread and post a link to this question.
Second both posts are in the wrong category. This question is
really for the Printed Documentation category but leave it now.
Is the chapter actually in the print layout. Often people see
the TOC layout and assume it is a mirror of the real TOC. When you
first create the printed output, it is. However any subsequent
changes to the TOC are not automatically made, you have to do that
Try that and also take a look at the Printed Documentation
article on my site.
