big problems , help !!!

I am working on a web-site which has a bunch of layers and a java script which controls their appearance. That means that I have the whole site in one html. The problem appeared when I tried to put php code inside a DIV tag. In that case only that layer was visible. I don't know weather php and java has problems working together. You can see the original page without php on http://www.okspartak.f2s.com/moj/ Php's role would be to show the tme from the last update and the passsword input for private zone of the site. Thanks in advance Nikola
