search script help

I recently found this search engine script while searching the net
recently and desperately need help with it. The script displays search
hippo results via xml feed and the sponsored results on the right hand
side are from revenue pilot. The script works except there is a bug.
The first query works fine (it displays 10 results per page) however
when you click "next" to go to the next page it will display 15 and
next page it will display 20 then 25 and so on. The other problem is
that the table size of the search hippo results on the odd occasion
will get bigger and will throw the revenue pilot results on the right
hand side out of view. I imagine that someone with knowledge of these
things would be able to rectify it quite easily, however this is a bit
above my head. If somebody could help me with this it will be very
much appreciated.

Here is the search results file (search.php)
