if { labels

[untitled88]

I can create an if statement for # of selected items. However, how can I create an if statement for even.label?
I have various labels and would like to create if statements based on if the text in my "labels" match up.

function handle_checkbox_change(event:KcheckboxEvent):void {
    trace("value before change : " + event.from);
    trace("new value : " + event.to);
    trace("checkbox group : " + event.group);
    trace("checkbox label : " + event.label);
    trace("checkbox attached data : " + event.data);
    trace("selected items : " + Kcheckbox.get_selected_items_of("group1"));
    
    if (Kcheckbox.get_selected_items_of("group1").length==1) {
        Tweener.addTween(testbox1,{y:222,time:1,transition:"EaseInOutBack"});
        trace("1 item is selected");
    }
