In need of help ASAP on Validation

I am validating my website in W3schools and i get 1 error saying 'Missing xmlns attribute for element html. The value should be: http://www.w3.org/1999/xhtml'

But when I change to this I then get 24 errors!what is going on?what is this xmlns attribute?

To change it I take my html out and replace it with: html xmlns="http://www.w3.org/1999/xhtml">

what am i doing wrong?

what am i doing wrong?

Posting the same question twice for one thing...lol


You might get a few more errors by fixing one. That happens sometimes. You NEED a complete doctype though, so keep that added in and then work on the other errors.
