Hi,
It seems that Internet Explorer 6 insists on a certain format of script tag, like this:
<script language="JavaScript" src="<url to your script>"></script>
Does this help? If not, can you please post the lines you are changing, before and after the change. Finally, is there any information in the browser status bar at the bottom left corner when you get your empty page?
Hope this helps.
