Scaling objects with AS2

What I am trying to do can't be that difficult. I just can't seem to find the answer.

I have a purple box on the stage. I turned this box into a movie clip with the instance name of "purple." onEnterFrame, I want to increase the wdith of that box. It is currently 11.75px. I want it to ease into 40px. I want this to happen onEnterFrame.

I am using Actionscript 2.

Any ideas?

This will change the width of the box:

purple._width = 40.0;

I dont know about the "ease" part but this should increase the size incrementally

Actionscript Code:

this.onEnterFrame = function(){
purple._width += 3;
if (purple._width >= 40){
delete this.onEnterFrame;
purple._width = 40;
}
}

There are a few approaches that can be taken.
1.

PHP Code:

---

this.onEnterFrame = function() {
    purple._width = 40;
} 


---

2.

PHP Code:

---

this.onEnterFrame = function() {
    purple._width += 4;
    if(purple._width > 40) {
        purple._width = 40;
    }
}

3.

PHP Code:

---

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

this.onEnterFrame = function() {
    var txw:Object = new Object(purple, "_width", Regular.easeOut, 11.75, 40, 1, true);
}
