Magento Checkout error, perhaps JS issue?

I have a Magento cart that's not checking out properly. If you go to [login to view URL] and then click add to cart, and then proceed to checkout you'll see that there is no input fields to enter when checking out. I had it on SSL before and right now it's with SSL disabled, any ideas? I need this done today! I really have a low budget as I've spent hundreds on this site already and its still not done
