Are you sure it's the last row you're not getting, and not the first?
I think your problem is you're trying to fetch the category with
mysql_result, then using mysql_fetch_array() to get the data.
From the PHP manual on mysql_result():
"Calls to mysql_result() should not be mixed with calls to other
functions that deal with the result set."
Perhaps you should get your category description after you fetch the
contents for the first row.
Another option would be to run a query to fetch just the category
description, rather than return it in every single row (just to save a
query). At some point the extra data returned will take longer than a
second select statement.
