Simple AS movement problem

1

I have an mc on stage for 300 frames. i have this code on the mc:


onClipEvent(enterFrame) {
    speed = .1;
    this._xscale += speed;
    this._yscale += speed;
    this._x -= speed*5;
    this._y += speed*2;
    
}

this moves the mc and resizes it slowly.

My problem is that in the last 15 frames that it is on stage I want it to fade out.

Any suggestions?

thanks
