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.

This thread is more than a year old. Please don't revive it unless you have something important to add.
