okay the situation is this:
the index.php page code is this: (this gives me a undefined error on line3 which is the line that begins with if)
<?php
session_start();
if ($_SESSION['user_logged'] == "" || $_SESSION['user_password'] == "")
{
include "unlogged_user.php";
}
else
{
include "logged_user.php";
}
?>
Now if the User needs to be REGISTERED it brings you to the registration page which is below which gives me an undefined error beginning with (if ($_POST['submit'] == "Register")) line 11.
code:
<?php
session_start();
include "conn.inc.php";
?>

<head>
<title>Beginning PHP, Apache, MySQL Web Development</title>

<?php

{
$check_user = $_POST['username'];
$query = "SELECT username FROM user_info WHERE username =
'$check_user';";
$result = mysql_query($query) or die(mysql_error());
if (mysql_num_rows($result) != 0)
