Setting a cookie?

[HDFilmMaker2112]

This is the first I've tried using cookies for a website. The below isn't setting a cookie.

 

I have my log-in form on the home page. Which submits to this script "login.php", if the credentials match the database, then it redirects to index.php?home. On ?home I'm trying to echo out the cookies and they're coming up blank. I also checked the cookies set in my browser, and the only one set for this domain name is the PHPSESSID.

 

 

The $login_stay_logged_in variable is set and it does = yes.

if($login_stay_logged_in=="yes"){
$hased_value = kam3(md5(generatepassword()));
$hashed_username = md5s($rows["email_address"]);
$time = time();
setcookie("emtco_hash", $hased_value, time()+(86400*180), "/", "beta.area51entertainment.com");
setcookie("emtco_username", $hased_username, time()+(86400*180), "/", "beta.area51entertainment.com");
setcookie("emtco_visited", $time, time()+(86400*180), "/", "beta.area51entertainment.com");
}

 

 

if(isset($_GET['home'])){
$content.='
<div class="left"></div>
<div class="center">'.$_SESSION['username'].'<br /> '.$_SESSION['password'].'<br /> '.$_SESSION['login_stay_logged_in'].'
<br />'.$_COOKIE["emtco_hash"].'
<br />'.$_COOKIE["emtco_username"].'
<br />'.$_COOKIE["emtco_visited"].'</div>
<div class="right"></div>
';
}
