How can I assign a var into a target path? This seems like it should work but the alpha is not changing. All my MC’s inside map are named to match the labels in the node passed from the XML file. Thanks in advance.

```auto

var myTreeDP:XML = new XML();
myTreeDP.ignoreWhite = true;
myTreeDP.load("xml/menu.xml");
myTreeDP.onLoad = function() {
 myTree.dataProvider = this.firstChild;
};
var treeListener:Object = new Object();
treeListener.change = function(evt:Object) {
 var menuClk = evt.target.selectedNode.attributes.label;
 trace(menuClk);
 _root.map[menuClk]._alpha = 100;
};
myTree.addEventListener("change", treeListener);

```
