They send you an email so you can verify your account. Justin.
Go back to your e-mail address and read the e-mail from the facebook team
When you sign up, you would have to have put in an email...you have to go to your email and see your inbox...and then you click where it says verify on your verification from the facebook website and then go back to facebook to log in!
There should be a link in the email they sent you with the code.
