[SOLVED] losing cart contents

[eluser]Ray G[/eluser]
I am using the cart class and session and have set up the sessions to be stored in mysql database. I am autoloading the cart class. All the code seems to work fine until I send the cart to the checkout controller and all my userdata gets erased in the database. I am also using ajax call and jquery to add and update the cart. Right now I have just renamed the main controller(pnp) to chout and took out a few things just to test here is the code I have so far. Also I have not finished some of the code for the processing of the checkout, so please disregard some of that.

View checkout.php

View chcart.php

I pasted everything here just for reference but I guess my real question is, why am I losing my session data when I go to a new controller??

Thanks for the help
