Help!!! My site broke!

I inserted some html and javascript code (mostly html comment tags) into my pages and now my site isn't working and I can't revert! Please look over my code and tell me if I messed up on any validations. My HTML validator says there are no errors?

What exactly isn't working in it? It seems to be working fine here...

 

it's working fine, is this some kind of joke?

 

no problem... What exactly isn't working in it?

 

The site does load without any problems, but there is errors on the page.

 

Imozeb, just try it again because its running smooth, it has no problem man.

 

I'll take away the if statements I put to hide the error (if response.Text == entire page then do not print) and you'll see what I mean. The two function which broken are the login function in the header right side (it won't let you login, prints the entire page) and the list function at http://www.foreverplaying.com/script/lists/allgames.php (it prints the javascript)

 

Got it. It was a .htaccess problem. Any idea on how to get extensionless urls without actually changing all my files from .php?
