35758 URGENT Tracking Code

I need this today! The site, [login to view URL], has a php invitation code installed on this page [login to view URL] You can use the code prpr to login. What I need is for us to be able to track the code to who ever logs in and purchases tickets to the sales rep that sent someone to the site. This would be accomplished easily if we had an online affiliate program, however the clients are sent to the site via telephone. This is an easy project if you know PHP. Please contact me via the board ASAP if you have further questions. I will update this posting. Phelan NS Marketing
