(Windows 7, CS6)
I'm working on a book that's too complex for a single file, so I used the book file option.
After generating an index on the book file, a few times it seems page numbers are not appearing. I made the following format for entries:
<entry><em space><page number>(<comma + space><other page number>). But sometimes this appears:
<entry><em space><comma + space><page number>
That would mean the entry has been marked on an unnumbered page, which is, to my knowledge, impossible.
Anybody has a clue what has happened?
By the way, I did check whether there was any overflowing text in any of the files. There wasn't. Also choosing the option 'Leave out items in overflowing text' (my translation of the text in the Dutch version) doesn't make a difference.
Make sure all the documents in the book are open when you create the index.
Thanks for your answer, I hope to come back to it later.
