Jessie, it is important to know why the page breaks are
there in the first place - and why can't you remove them?
If they are part of a cross reference (as was my case) the
problem was that I had inserted the cross reference, then
put a hard page break in front of the heading to which the
cross-reference pointed. The solution is to take out the
manual page breaks, and place the cursor in the heading,
select Format/Paragraph/Line and Page Breaks/'Page Break
Before'.
I hope this is your problem, then it's easy to solve. Look
at my question in the topic 'Unwanted page break before a
cross-reference'
