<a href="javascript:ChangePage()"><img src="images/AmazonAd1_anim.gif" alt="Banner Advertisement" border="0" hspace="0" name="bannerad" WIDTH="466" HEIGHT="58"></a>
You also need to modify the <BODY> HTML tag of the page so that when the page is loaded, it executes the InitialiseBannerAdRotator function. Do this by adding the onload tag, as shown below:
<body onload="InitialiseBannerAdRotator()">
Finally, you need to add the following script to the page (within the <HEAD> part of the page is the ideal location):
<script language="javascript"><!--

}
