Creating moving clouds

Question

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);

Answer 1

all the clouds move initially, but then only one re enters?
    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
    MovieClip(event.currentTarget).x +=6;
    if (myCloud.x> stage.stageWidth)
        myCloud.x = 0;
Not quite sure what you mean about the width?
myCloud.width=?
