iWeb '09, Does anyone know why my HTML snippet is not working?

[Marcus B]

I go to my youtube channel and go to connect with my account box and at the bottom there is the embed code and I copy that and paste it where it tells you too on the HTML snippet and the part that is on the website is all white? SOMEONE HELP 10 POINTS IF YOU FIX IT

I've run into places where I had to actually type a code into the box. Copy and paste didn't work.
