'the variables' refers to the ones in $_SESSION ?

Are you relying on register globals ancient wrong settings in php.ini?
This code needs to be fixed IMHO.
<snipped a few pages of code>
Bulldog, you better start with a very simple page that uses a sessions,
and a followup page that tries to read the session.
That will learn you what is wrong without the complications of the old
(bad) script.
page1.php
<?php
session_start();
$_SESSION["test"] = "Testing";
?>
<html>
<head><title>testing</title></head>
<body>
<a href="page2.php">Session set, go to page2 to check its value</a>
</body>
</html>
page2.php
<?php
session_start();
?>
<html>
<head><title>testing</title></head>
<body>
SESSION CONTAINS:
<br>
<pre>
<?php print_r($_SESSION); ?>
<hr>
POST CONTAINS:
<br>
<pre>
<?php print_r($_POST); ?>
<hr>
GET CONTAINS:
<br>
<pre>
<?php print_r($_GET); ?>
<hr>
COOKIE CONTAINS:
<br>
<pre>
<?php print_r($_COOKIE); ?>
<hr>
</body>
</html>
Try something simple as this first, and see what happens.
