hi all,  
I’m writing function for hoover efect in dinamic xml menu.  
Function is working, but I got to shorten my code.

function hoover(){  
\_root.menu0.onRollOver = function () {  
this.\_alpha = 50;  
};  
\_root.menu1.onRollOver = function () {  
this.\_alpha = 50;  
};  
…  
}

I have number of menus in variable nMenu.  
How can I do this? Thanx.
