Problem beim ansteuren des mc?

[robinnitsche]

Hallo zusammen,
ich hab folgendes Problem ich hab einen einen Mc in den andere mc abgelegt sind. diese will ich nun anstreuern wenn ich über die combobox eine auswahl mache. komischer weise werden die mc in der unteren ebene aber nicht ausgewählt. ich hab schon den root mir dazu ausgeben lassen und von den instanzen namen passt alles. er steigt mir praktisch an der Stelle aus
trace(_root.campus.K-Bau_f2._currentframe);

Hier noch der ganze code:

PHP-Code:

onLoad = function() {
    _root.requestObjects("http://localhost/campus/campus.php");
}

stop();

this.myObjectXML = new XML();
this.myObjectXML.ignoreWhite = true;
this.myObjectXML.onLoad = function(sucess) { importObjects(sucess); }

//Arrays mit allen Daten
this.myObjectBau = new Array();
this.myObjectFak = new Array();
this.myObjectPer = new Array();
this.myObjectRau = new Array();


// Hilfsvariablen + Arrays für comboboxen anlegen
var building = new Array();        
var fakName = new Array();
var room = new Array();
var perName = new Array();


this.building.push("Wählen Sie");
this.fakName.push("Wählen Sie");
this.room.push("Wählen Sie");
this.perName.push("Wählen Sie");

// Füllen der arrays aus dem Xml
function importObjects(sucess) {
    if(sucess) {
