[SOLVED] Error with captcha

[jack bro]

I'm trying to insert captcha into my register page and need to know why this is working, link to register page is http://www.midcity-mafia.com/register/

 

Nothing happens when register form is submitted, here is relevant code:

 

if ($_POST['Submit']){
	// Define post fields into simple variables
	$reg_username = $_POST['reg_username'];
	$pwd2 = $_POST['pwd2'];
	$email = $_POST['email'];
	$email1 = $_POST['email1'];
	$location=strip_tags($_POST['location']);
	$ref = $_POST['ref'];
	$reg_username=trim($reg_username);
	$pwd2=trim($pwd2);
	$today = gmdate('Y-m-d h:i:s');
	$reg_username = stripslashes($reg_username);
	$email = stripslashes($email);
	$quote = stripslashes($quote);
	$reg_username = strip_tags($reg_username);
	$email = strip_tags($email);
	$resp = recaptcha_check_answer ($privatekey,
                                  $_SERVER["REMOTE_ADDR"],
                                  $_POST["recaptcha_challenge_field"],
                                  $_POST["recaptcha_response_field"]);

if (strlen($reg_username) > 3 || strlen($reg_username) < 40){
					$sql_email_check = mysql_query("SELECT email FROM users
            WHERE email='$email' AND status='Alive'");
					$sql_username_check = mysql_query("SELECT username FROM users
            WHERE username='$reg_username'");
					$email_check = mysql_num_rows($sql_email_check);
					$username_check = mysql_num_rows($sql_username_check);

						if($email_check > 0){
							$message= "Your email address has already been used by another player!";
							unset($email);
						}


						if($username_check > 0){
							$message="Your desired username is already in use, please choose another one.";
							unset($reg_username);
						}
					} elseif ($resp->is_valid) { //if captcha is vaild
						$userid = mysql_insert_id();
						$ip = $_SERVER['REMOTE_ADDR'];
						$random_password22=rand(11111,99999999);
						mysql_query("INSERT INTO `user_info` ( `id` , `username`)
VALUES ('', '$reg_username')") or die (mysql_error());
						mysql_query("INSERT INTO users (`id` , `username` , `password` , `regged`, `email`, `location`, `r_ip`)
VALUES ('', '$reg_username', '$pwd2', '$today', '$email', '$location', '$ip')") or die (mysql_error());
						$sql = "UPDATE users SET totalref=totalref+1 WHERE username='$ref'";
						mysql_query($sql) or die("Error executing: $sql" . mysql_error());
						$message= '<font color="#000000"> <br />Account created, </font> <a href="index.php"> 
<font color="#FFFF00">You may now log in.</font></a> ';
} else {
    $message = '$resp->error'; // Captcha error
  }
}

?>
