Sequence of Expanding Circles

I’ve been messing with some code from [SIZE=-1]lionbichstudios.com. I’m looking for a way to have 5 circles appear in succession and expand and fade away. Works fine for one circle but I haven’t found a good way to create a sequence of circles. The one hitch: the code needs to appear all in one frame. (I’m using Flash MX 2004)

Here’s the basic code:

[/SIZE]

//Eliminates Stage.width bug
Stage.scaleMode = noScale;
var c:Number = 5;
this.createEmptyMovieClip("blank_mc", 1);
blank_mc.onEnterFrame = function() {
    //currx = _root._xmouse;
    currx = Stage.width/2;
    curry = Stage.height/2;
    trace(Stage.width/2);
    if (!(prevx == currx && prevy == curry)) {
        _root.attachMovie("mc", "mc"+c, c);
        with (_root["mc"+c]) {
            _x = currx;
            _y = curry;
            _width = 0;
            _height = 0;
        }
        this._parent["mc"+this._parent.c].onEnterFrame = function() {
            this.i++;
            this._width += 1.4;
            this._height += 1.4;
            this._alpha -= 100/60;
            if (this.i>=60) {
                //this.removeMovieClip();
            }
        };
        _root.c++;
    }
    prevx = currx;
    prevy = curry;
};
