Are you talking about a XOOPS site? and that you have added the link to the footer of your [theme]/theme.html file? If so, you can add the link using
<a href="<{$xoops_url}>/termsofuse.html">Terms of Usea>
if you put your file in the root directory of your XOOPS site. Of course, I'm just guessing here, we need more information, like Mithrandir said.
