Page numbering
Another useful tip. I got resolve a problem with the index table. Never use the Offset feature you can see in the page number field dialog! The ToC (Table of Contents) is based on the real page numbering, it doesn't take into account the offset feature. Moreover, your last page won't have any numbering if the correction is positive.
* Go to the first paragraph of the page to be renumbered, right click and select Paragraph.
* Go to the Text Flow tab, in the Breaks section, adjust the page number.
