Site Working Offline, Not So Much Online?

i have this site everything works perfect offline(local) but when i put it on my server theres a few things that mess up. What isnt working.. I have a little readmore link beside a main quote on everypage and this uses ceebox to open it. Within this lightbox it shows an html page that i made with just a little write up, at the bottom is a little nav and onclick it should be opening the corresponding hidden div while closing the lightbox. this works offline perfect, i cant seem to figure out why it wont once uploaded. I have gone over all folder names, etc and im positive this isnt the problem. this is the main page html snippet with the read more link

Code:
<div id="header-fade">
<div class="header_paragraphs panel" id="header-1" style="z-index: 0;">
<div class="header_p_1"><p class="header-p">AAAAAAAAAAAAAAAAAAAAAA</p></div>
<div class="header_p_2"><p class="header-p">AAAAAAAAAAAAAAAA</p></div>
<div class="header_p_3"><p class="header-p">AAAAAAAAAAA</p></div>
<div class="header_p_4"><p class="header-p">AAAAAAAAA</p></div>
</div><!-- Header P's -->

[Code]...

again it all works offline but as soon as i uplaod it to my server the nav inside the lightbox doesnt seem to work.
