JavaScript HELP!

This is the HTML and Java code that I have been using forever on my flash sites. I recently designed a client site at 1024 x 768 and if viewed at 800 x 600 they can’t see it becuase it’s set not to scale. My problem is they don’t mind it being bigger than the screen but this java doesn’t allow for scroll bars. If someone can look over the code and help me out that would rock!!!

Thanks
