How do you remove a page break?
If it's a manual page break (inserted with Ctrl+Enter or the Insert >
Break dialog), you can just select it and press Delete as with any
other character. This is easier to do if you switch to Normal view so
you can see the break.
If it's some form of section break (next page, odd, or even) you can
do the same, but be aware of the section-formatting problems you might
have -- see
http://www.word.mvps.org/FAQs/Formatting/WorkWithSections.htm.
Page breaks can also be caused by paragraph formatting of "Page break
before" or "Keep with next", in which case the solution is to remove
that formatting (Format > Paragraph > Line and Page Breaks).
There are other causes, some of them fairly obscure. If the
suggestions above don't help, post back.
