fix small error and add live chat to osc site

I need someone to fix a small error on my oscommerce site. When the viewer clicks the next button it does not got to the next page to see the next page of items, and I would like it to be corrected so that when they click next it actually goes to the next pages, and does not stay on the current page. I alsi need a live chat added to my website. I need this done now. I refuse to pay more then $30 for this project, so dont waste time please. Thanks
