Hoping someone can point me in the right direction

Hi All,

I need a little advice. my employer has asked me to re-build a 10 year old site, here's the link:

http://www.autocolorlibrary.com/

The shop works, contact forms yep... but I'm having trouble getting the year and make selectors to display the color book pages with the order form... Anyone have any thoughts on getting this to work in perch? Or if you could point me in the right direction that would be appreciated.

Thank you,

Chad
