Item label displays as "," when moving from listbox to listbox

[quadrant6 webforumsuser@macromedia.com]

I have 2 listboxes: "lb_unselected" and "lb_selected". The first thing in the actions is loop through an array populating these two listboxes.

There is also an "add" button which, when clicked moves the currently selected item from the "lb_unselected" listbox to the "lb_selected" listbox.

The problem is that, although the item is moved to the "lb_selected" listbox, it displays as "," - the label changes to this when it's moved?

I am sure this is something to do with the array index? but cannot figure out what exactly.

Any insights would be appreciated.


// Code that populates both listboxes:

for(n=0; n<allItems.length; n++) {
is_selected = false;
for(i=0; i< allItems[n]['topics'].length; i++) {
if(allItems[n]['topics'][i] == topic) {
lb_selected.addItem(allItems[n].item_name, allItems[n].item_id);
is_selected = true;
break;
}
}
// fill Unselected items listbox
if(!is_selected){
lb_unselected.addItem(allItems[n].item_name, allItems[n].item_id);
}
}



//Code that the add button activates:

// add item
function addSubcat(listIndex) {
// add item to Selected list box
lb_selected.addItem(lb_unselected.getItemAt(listIn dex).label, lb_unselected.getItemAt(listIndex).data)

// select and sort new item in Selected list box
lb_selected.setSelectedIndex(lb_selected.getLength () - 1);
lb_selected.sortItemsBy("label", "ASC");

// remove good practice from Unselected listbox
lb_unselected.removeItemAt(listIndex);
}

Answer: incorrect function names.
