Have you tried just invoking:

Code:

<script type="text/javascript">

ajaxpage('ben.htm', 'contentarea')

</script>

With the above added to the end of your page?

You have to place the <script> after the <div> that it is affecting. The browser runs through the code and executes it in the sequence you have it in your HTML. So when it gets to the <script> it tries to load the content into the <div> you specified, but that div doesn't "exist" yet because the browser hasn't gotten to that line.

I've found it the safest to place your <script> at the end of the document, just before the closing </body> tag.

Like this:

<body>

<div id="rightcolum"></div>
<a href="javascript:ajaxpage('ben.htm', 'contentarea');">test</a> <div id="contentarea"></div>

<script type="text/javascript">
ajaxpage('ben.htm', 'rightcolumn')
</script>

</body>
