hvorfor virker dette cookie script ikke.....

<script>

function setcookie(name,value) {
  today = new Date;
  expires = new Date(today.getSeconds() + 30);
  document.cookie=name + "=" + escape(value) + "; expires=" + expires
}

function getcookie(name) {
  cookielist=document.cookie.split(";");
  for ( count = 0 ; count < cookielist.length ; count++ ) {
    if ( cookielist[count].split("=")[0] == name )
      return unescape(cookielist[count].split("=")[1])
  }
  return null;
}

function showvisits() {
  if (!getcookie("test")) {
  // setcookie("test","hej");
  document.write("<p>OBS! Du har ikke slået cookies til</p>");
  }
}
</script>
