Firstly, thank you very much for the reply - I appreciate it.

Nope - all I did was this:

I see.

Interesting... When I go to
http://www.contracting-online.com/home/default.aspx and do a View Source, I
most certainly _do_ see the <meta> tag... Is it normal for the validator to
ignore the <meta> tag? Or maybe I have not written it correctly...?

I didn't know that. I maintain loads of sites, and they all validate 100%
except this one... Not sure what to try next, so would be very grateful for
any suggestions...

Thanks again for the reply.
