cookies dont go away!

[zzzreyes]

so I set a cookie to use my chat php program and be able to remember the user each time he comes...
so he goes trough the registration page, then a cookie is set as follow
$CookieString=$FirstName.'&'.$LastName.'&'.$email.'&'.$count;
SetCookie ("Example",$CookieString, time() +99360, "/chat/", "DomainHere.com");

Now I want to be able to clear this cookie out in case someone else wants to use the computer.
so I redirect them to clearcookie.php
<PHP SetCookie ("Example","", time() -99360, "/chat/", "DomainHere.com"); ?>

then it goes to the registration page again... so its back to step 1.

BUT THE COOKIES R NOT LEAVING!!!!!!!!
