[Zope] internal links?

I am trying to use a simple internal link: <a href="#jump">jump to further down the page</a> . . . . <a name="jump">you should end up here</a> Zope wants to add a '/' to the end of the base link so I am using: <a href="<dtml-var URL1>#jump">jump to another part of page</a> instead but this wants to refresh the page before going to this section. Any help appreciated.
