I’m using FlashCS3 with AS2.0. I am trying to create a movieclip button which controls the properties of another movieclip.

In my actions layer I have:  
import mx.transitions.Tween;  
import mx.transitions.easing.\*;

On my movieclip:  
on(release){  
\_root.attachMovie(“myform”,“myform1”,200);  
\_root.myform1.\_x=200;  
\_root.myform1.\_y=200;  
var fading:Tween = new Tween(myform1, “\_alpha”, Elastic.easeOut, 0, 100, 10, true);  
}

It gives me the error message of not being able to load the tween class.  
Can someone help me with this?

Thank you.
