i’m stumped, i want to create 2 types of button functions… a “onRollOver” and a “onRollOut” function.

…that way my Btn script will look like this:

\*\*navMain.about\_btn.onRollOver = function(){  
rollOn();  
}  
\*\*

FYI: the buttons i want to effect are nested inside navMain

so, this what i have so far:

import mx.transitions.Tween;  
import mx.transitions.easing.\*;

function rollOn(){  
var rollOnBTN:Object = new Tween(_I DON’T KNOW WHAT TO PUT HERE_, “\_xscale”, Elastic.easeOut, 100, 140, 1, true);  
var rollOnBTN:Object = new Tween(_I DON’T KNOW WHAT TO PUT HERE_, “\_yscale”, Elastic.easeOut, 100, 140, 1, true);  
}
