error...

My page validates for W3C XTHML, so I place the valid xhtml image and corresponding uri on my page as seen below:

<p>
      <a href="http://validator.w3.org/check/referer"><img
          src="http://www.w3.org/Icons/valid-xhtml10"
          alt="Valid XHTML 1.0!" height="31" width="88" /></a>
    </p>

On clicking the image I was redirected to the following url:
http://validator.w3.org/check?uri=

Thanks,

Harry
