fade - alpha

does anyone know a way that I can tell movieclip to fade by placing the code in a frame. I've seen ways of doing it using buttons but when I try to redo the code it doesn't work.

basically I have 4 frames with 4 different movies in them. When you go to, lets say, frame 2 movieclip 2 fades. When you go to frame 3 movieclip 3 fades and etc.

Any ideas or tutorials. Never used alpha before.

code:

---

function fade(target, destination) {

rate = 10;

target.onEnterFrame=function() {

rate = rate*.95;

if (this._alpha == destination) {

delete this.onEnterFrame;

}

this._alpha += Math.round((destination-this._alpha)/rate);

}

}

---

put that in frame 1 of main timeline.

anytime you want to use it on a mc, just put fade(x,xx) and substitute the thing you want to fade for "x" and the alpha you want it to get to for the "xx", like this

code:

---

on(press) {

fade(_root.somemcinstancename, 0);

}

Thanks worked swell...
