"It's not working" is pretty vague. Are you getting any errors? Is the page echoing "ERROR"? Does everything "seem" to work, only you never receive the email? What do you get if you put var_dump($to, $subject, $info, $header); on the line right above mail()?
Haha, funny story, all that was missing, very start of the form tag, the action script was blank. It wasn't pointing to the contact.php folder! But now, onto the PHP file, how do I get my radio buttons in the email?
