Tænd/sluk musik

Nogen der kan se hvor jeg har lavet fejl? evt. kan rette den? :)

<?

ob_start();
$music = strip_tags($mus);

if($music == "stop") {
setcookie ("LoveMusic", stop);

setcookie ("LoveMusic", stop,time()+36000000);  /* expire in 1 hour */

setcookie ("LoveMusic", stop,time()+36000000, "/~rasmus/", ".utoronto.ca", 1);

echo"<A HREF=$PHP_SELF??mus=start>Start Music</A>";
elseif($music == "start") {
setcookie ("LoveMusic", start);

setcookie ("LoveMusic", start,time()+36000000);  /* expire in 1 hour */

setcookie ("LoveMusic", start,time()+36000000, "/~rasmus/", ".utoronto.ca", 1);

elseif (isset($_COOKIE["LoveMusic"])){

$value = $_COOKIE["LoveMusic"];

if($value == "stop") {
