[javascript] Menu

Bonjour,
J'ai trouvé un script pour faire un menu déroulant qui est censé monter et descendre en même temps que la page. Mais voilà, il ne monte et ne desend pas et je ne trouve pas la solution.
Voici le code :


/*
POUR AJOUTER DES LIGNES DANS LE MENU, VOIR A LA FIN DU FICHIER (ligne 182)
*/
