Del af menu åbner ikke.

Jeg har gennemgået min menu hvor punktet 'Special tilbud' og punktet Golf under Sport ikke åbner sig.
Sitet er www.orkiderejser.dk

Er der en venlig sjæl der kan se hvad fejlen er:

Javascript koden er:
foer = null;
function fold(id) {
  obj = document.getElementById(id);
  if (foer != null && foer != obj)
    foer.style.display = "none";
  obj.style.display = (obj.style.display == "none") ? "inline" : "none";
  foer = obj;
}

html koden:
