below is an example of my code.

! the mc only tweens once. why??? !

the myVar traces correctly on every roll over. but the mc only tweens on the first roll over.

* * *

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

var myVar:Number = (mc.\_x + 35);

button.onRollOver = function(){  
trace (“Roll Over”);  
trace (myVar);  
var mytween:Tween = new Tween (mc, “\_x”, Strong.easeOut, mc.\_x, myVar, 1, true);  
}
