I must admit… I am not programming with classes - mainly because I’ve bought somescripts online and did not manage to modify them into classes since I’m of the victoms of AS3’s learning curve!

I’ve created a tab menu (code is on the main timeline, in a function called xmlLoadedNews) and builds tabs like this :

```auto

xmlListLength = xmlList.length()

for (var i:uint=0; i<xmlListLength; i++) {

        var newsTab = new NewsTab();
        tabHolder.addChild(newsTab);
        newsTab.name = i;

```

Now, I’ve got another script running in a child MC that wants to replace the “xmlList.length()” with the results of playersXML :

```auto

var playersXML = xml..event[evt.target.id].players.player.length();

```

How may I change the variable from xmlListLength to playersXML in the parent MC?
