OH I hate it when I figure the problem out 15 min after posting.
Anyone else having this problem, it is "Register globals". If your ISP has them turned off, then you'll need to put in an .htaccess file in your classifieds folder
with the following - php_flag register_globals on
Or I am sure there is a place in one of the files to do this, But I am too tired to look at the code right now.
