XHTML Validation - Image Maps

ev5unleash · April 10, 2009

I'm trying to use image maps on my page but it seems something I'm doing in W3C's is wrong. Please tell me what this error message means and how I could fix it. http://validator.w3.org/check?uri=http://ev5unleash.dnsalias.org:85/websites/biosite/layout.html;accept=text/xml,application/xml,application/xhtml%2Bxml,text/html;q%3D0.9,text/plain;q%3D0.8,image/png,*/*;q%3D0.5;accept-language=en-US,en;accept-charset=ISO-8859-1,*,utf-8

Thanks, Evan

Thank link times out, so we can't see what the error is.

I have one image map on my site and the only difference I saw is that my <map><area /></map> comes before my image in my HTML. However, without actually knowing what error you're getting, I can't offer much more advice.
