Creating moving clouds

Hi

I have this assignment where we have to use a display list. I am trying to create clouds moving on the background.

I'm sure my code is very clumsy. I was able to get the clouds on my stage but I can only get one to move.

Please, I can't seem to wrap my head around this and as you can see I'm a novice.

import flash.display.*;

import flash.events.*;

var myBackground:BackGround = new BackGround();

addChild(myBackground);

var myCloud:MyCloud;

for (var i:Number = 0; i<6; i++)

{

    myCloud = new MyCloud();

    addChild(myCloud);

    var randomValue: Number = Math.random()*2;

    myCloud.x = Math.random()*stage.width;

    myCloud.scaleX = myCloud.scaleY = randomValue;

}

    myCloud.addEventListener(Event.ENTER_FRAME, flyBy);

    function flyBy(event:Event):void

{

    myCloud.x +=6;

    if (myCloud.x> stage.stageWidth)

    {

        myCloud.x = 0;

    }

}

addChild(myCloud);
