Like the /form and /center tags enter the form.

Can you provide the source code and/or the page with the error(s) on it? Thank you.

I wouldn't recommend u go there, cause its one of the popup message sites I'm starting. :)

Yes, I actually went through that whole thing to view your source. :P

I don't think you need the <form> tag at all... and you forgot to close your textarea with </textarea>, so that might cause a problem as well!
