This one has me stumped. I’m missing a trick here I think; so why doesn’t this work?

```auto

function makeClouds(clouds:Number) {
    for (var i=0; i < clouds; i++ ) {
        var cloudName:String = "cloud" + i + "_mc";
        var cloudStart:Number = Math.round(Math.random() * Stage.width);
        this.attachMovie("cloud_mc", cloudName, this.getNextHighestDepth()); 
        debugMessage(cloudName);
        this[cloudName]._x = cloudStart;
        this[cloudName].onEnterFrame = function() {
            debugMessage("moving: " + cloudName);
            
            if (this[cloudName]._x <= -100) {
                this[cloudName]._x = Stage.width;
            } else {
                this[cloudName]._x -= 3;
            }
        }
    }
}

```

The cloud mcs attach fine and are displayed… but only one of the buggers animates. No errors are displayed. Help!
