Script-Fehler: Was mach ich falsch?

[christopher]

Hallo,

ich habe dieses Script im Internet Gefunden. Nun meine Frage: Warum wird das Untermenü bei Mindstorms ... nicht geöffnet????

//Create main menu
var menu = new menuObject("menu",pageWidth/2,pageHeight/2,"Sitemap",pageHeight/2);
menu.startAngle = -90;

//show menu and caption
menu.show();
menu.showCaption();

//Add submenus
menu.addItem("Über mich","window.open('uemi.php')");
menu.addItem("Meine Familie","toggle");
menu.addItem("Fotoalbum","toggle");
menu.addItem("Freunde","window.open('freunde.php')");
menu.addItem("Hobbys","toggle");
menu.addItem("Downloads","toggle");
menu.addItem("Kontakt","toggle");
menu.addItem("Chat","window.open('freunde.php')");

menu.subMenus[1].addItem("Mein Vater, meine Mutter, mein Bruder","window.open('vater.php')");
menu.subMenus[1].addItem("Meine Hunde","window.open('hund.php')");

menu.subMenus[2].addItem("Harzurlaub 2002","window.open('harz.php')");

menu.subMenus[4].addItem("Programmierung","toggle");
menu.subMenus[4].addItem("Violine","window.open('geige.php')");
menu.subMenus[4].subMenus[0].addItem("Mindstorms","toogle");
menu.subMenus[4].subMenus[0].subMenus[0].addItem("Was ist Lego Mindstorms?","window.open('mindstorms.php')");
menu.subMenus[4].subMenus[0].subMenus[0].addItem("Programmierung","window.open('m2.php')");
menu.subMenus[4].subMenus[0].subMenus[0].addItem("Nauanleitungen","window.open('m3.php')");
menu.subMenus[4].subMenus[0].subMenus[0].addItem("Tipps und Tricks","window.open('m4.php')");

menu.subMenus[5].addItem("Schule","toggle");
menu.subMenus[5].subMenus[0].addItem("Referate","toogle");
menu.subMenus[5].subMenus[0].subMenus[0].addItem("Erdkunde: Amerika","window.open('daten/schule/.zip')");

menu.subMenus[6].addItem("EMail","window.open('mail.php')");
menu.subMenus[6].addItem("Gästebuch","window.open('')");
