I actually do have a "homepage.tpl" It is what controls the center section of the customer side. (where "welcome to" starts) I don't know if it was written specifically for our cart, I guess maybe it was since you say that x-cart dosen't have this file by default.
Anyway, I finally got it to work. I had too many lines and spaces in the code. It was breaking the page, so I condensed all the JS down to have no extra empty lines between the code. This is what I placed at the very top of the file
