Need some serious layout help

I have no idea what has happened, but somehow my site is all messed up now. I am working on http://www.cartoolconnection.com

In Firefox my site shows up alright. But in Safari and in IE all my right hand sideboxes are gone and so is my footer. Any ideas? Also in Safari it chops half my page off. I don't understand why this is happening.

You main image on your main page does not appear to be centered. The image may be too wide for your template or you may have placed some odd code into the page (using Define Pages in admin).

I have viewed your site with FF and yes - the right hand sideboxes are truncated on their left hand side.

Thanks for the help! I did find the solution...the culprit was this little critter:

-->

Not sure what it is, but I deleted it and everything went back to normal. Not quite sure how it wheedled it's way into my code, but it's gone now.

the symbol is html code - explanations here:
