make sure your global variables are set up in your server:

then you need to set it up in your file on the first line

also, make sure you hare putting this at the very top of your page try this first:

put this code at the top of your script

session_start();

if that doesnt work, try the next step

put this code at the top of the page to set global variables from within the script

ini_set('register_globals', true);

ok, you last resource to troubleshoot is see what the value of $key is,,, you said earlier that its empty.

so put this at the top of the page or declare $key as $_SESSION['key']

so lets try the first step and compare these two. put this code at the top of your script and give me the output:

PHP CODE:

<?php
echo '$_SESSION[key]: '.$_SESSION['key'].'<br>';
echo '$key: '.$key.'<hr>';
?>

OUTPUT:

$_SESSION[key]: da470
$key:

ok so when you compare your input with the key, dont user $key, change your code:

FROM:

LINE: 102 if($number!=$key || !$number) {

TO:

LINE: 102 if($number!=$_SESSION['key']|| !$number) {
