You can't access a cookie before it's set.

$challenge = $HTTP_COOKIE_VARS["challenge"];
This is assigning the value of a cookie named "challenge" to a variable named $challenge. At this point, there is no cookie named "challenged".

setcookie("challenge","yes",time()+14400,"/",".neverplaysober.com",0);
This is creating a cookie named "challenge". Only after you have created this cookie can you access it.

I think what you want is this:

<?php
if (isset($HTTP_COOKIE_VARS[\"challenge\"])) {
    // user has been here before
    print (\"Try again in 4hours!\"); 
}
else {
    include 'challenge1.php';
}
?>

ok, I've set up 2 pages.. one with this code.. The include page has a form that will be sent to a page that mails me the submited info. Then it's forwarded to another page that has a cookie.

Form page
------------------------------------------------------------

<?php
$challenge = $HTTP_COOKIE_VARS["challenge"];
$challenge1 = $HTTP_COOKIE_VARS["challenge"];
if ($challenge == "$challenge") { 
print ("Try again in 4hours!");
} else {
include 'challenge1.php';
}
?>

-----------------------------------------------------------
cookie page

<?php
setcookie("challenge","yes",time()+14400,"/",".neverplaysober.com",0);
?>

Now the form page works fine If I visite the cookie page first. If I visit the form page first I get the following errors..

Notice: Undefined index: challenge in C:\Inetpub\finalphase\neverplaysober\v4\test\challenge.php on line 8

Notice: Undefined index: challenge in C:\Inetpub\finalphase\neverplaysober\v4\test\challenge.php on line 9
I like blue too!

You can't access $HTTP_COOKIE_VARS['cookie'] because you haven't yet set that cookie variable.

try lowering the error_level:

<?php
error_reporting(7);
$cookie=$HTTP_COOKIE_VARS['cookie'];
setcookie (\"cookie\", \"test\", time()+3600);
?>
