Hi guys, I'm using the HTML 5 boilerplate and trying to follow some instructions from a text book but nothing is drawn. Firebug says "document.getElementById is not a function" but it is! Confused. Any help appreciated. Thanks!

That can't happen unless one of the applications you loaded has overwritten the document or getElementById() properties. Could you provide a test page we can check?

you have to open the firebug before you load it. if you load the site first and then open firebug you wont see anything.
