Real Simple History [Please no jQuery]

So am trying to implement RSH on my ajax site but its not working i cannot even get the hashes in my url can anyone help my code is below

<script type="text/javascript">

	window.onload = function() 








<li id="articles"><a href="javascript:newarticle()" onclick="dhtmlHistory.add('newarticle.html','link')">Articles</a></li>

<li id="favourites"><a href="javascript:displaybookmarks()" onclick="dhtmlHistory.add('bookmarks.html','link')">Favourites</a></li>

<li id="archive"><a href="javascript:pagenation('Listing','1')" onclick="dhtmlHistory.add('archive.html','link')">Archive</a></li>

function historyChange(newLocation, historyData)


ShowOldContent(newLocation, historyData);

// OR to simplify

alert('hey I am going back to ' + newLocation);


I followed a tutorial but still no go. My back button is using the function javascript:history.back(). Anyone can point out where I am going wrong?
