Combobox wont go to function or data problem?

i have a problem with my combobox

code:

var images = xmlNode.childNodes*.childNodes[3].childNodes.length ;
for (img=0; img<images; img++) {
Name= “image” + img;
imageloc = xmlNode.childNodes*.childNodes[3].childNodes[img].firstChild.nodeValue;

list.addItem({label:Name, data:imageloc});
//dropDown.setChangeHandler(“SelectItem”);
trace (Name);
trace (imageloc);
dropDown.addItem(Name, imageloc );

}
dropDown.setChangeHandler(“SelectItem”);

function SelectItem(){
imageloc2 = ( dropDown.getSelectedItem().data);
_root.imagearea.loadMovie(imageloc2, 1);
}

what have i done wrong? it loads the names perfectly …
my guess its the data where it goes wrong

but it doesnt seem to recognise the
dropDown.setChangeHandler(“SelectItem”);

or it wont call the function

please help me out.
