Making the following 2 changes will fix it..

 

1 - change the text on your submit button, currently you have spaces  " Register " , but in your PHP you are not checking for spaces you just have

 

if (isset($_POST['submit']) && $_POST['submit'] == 'Register')

So change your submit button to...

 

<input type="submit" value="Register" name="submit" id="submit"/>

 

then I always find wrapping my if statements in brackets is far better as it none of it will get run unless it passes your checks u are doing, so for example use this..

 

if (isset($_POST['submit']) && $_POST['submit'] == 'Register') {

        $query = 'INSERT INTO nelyn_user
                (user_id, username, password, email)
           VALUES
               (NULL, "' . mysql_real_escape_string($email, $db) . '", ' .
                     '"' . mysql_real_escape_string($username, $db)  . '", ' .
         'PASSWORD("' . mysql_real_escape_string($password, $db) . '"))';

   $result = mysql_query($query, $db) or die(mysql_error());
   $user_id = mysql_insert_id($db);


        $_SESSION['logged'] = 1;
        $_SESSION['email'] = $email;

        header('Refresh: 5; URL=login.php');      
}

 

Hope that helps and all make ssense
