Pagination II

Thanks to everyone here, I am closer to getting this working but am
still having a problem....
The script runs and outputs a page, but in the db I have set up all of
the categories have enough entries to fill multiple pages. So, the
script runs and always goes to page 2 for some reason.
And if I click on one of the other links for a different page, then I
get nothing on that one.
Can anyone spot the problem?
Thanks in advance,
Jim
