OnEnterFrame - attachMovie

This should be easy for someone, I’m trying to attach a bunch of movieClips to the stage and have it animate this action using onEnterFrame.

everthing works but i would like all the mc’s to stay on the stage. right now it deletes the old one after it makes a new one.

var nStage:Number = Stage.width;
var nXpos:Number = 0;
var nCurrent:Number = 0;
onEnterFrame = function () {
    if (nCurrent>=nStage/10) {
        delete this.onEnterFrame;
    } else {
    attachMovie("mcStick", "newStick"+nCurrent, nCurrent);
    ["newStick"+nCurrent]_x = nXpos;
    nXpos += 10;
    _alpha = 10+Math.random()*40;
    _y = random(Stage.height)/2;
    _yscale = 50+Math.random()*100;
    nCurrent += 1;
    }
};

any help you could give would be wonderful - thank you
