Hi Jason,
The errors look like this in the browser.

My pages will be attached at the bottom. I've never done this before so bear with me if I didn't send enough files. The problem is on the I_full_width_product_page_l.php and I sent my cart page as well. Many thanks already for getting back to me so quickly.
