AS3 moving clips in array not working

Question

I'm having three movie clips, which I would like to move randomly within a set box. The following script works with one movie, but not with all movies placed in an array.
Please help!
var clipSpeed:Number= 1;
var speedX:Number = 0
var speedY:Number = 0
var upperLeftLimit:Point = new Point(0, 0)
var bottomRightLimit:Point = new Point(300, 300)
var clipArray:Array= [clip, clip1, clip2];
for (var i=0; i<clipArray.length; i++)
trace (clipArray[i])
clipArray[i].addEventListener(Event.ENTER_FRAME, randomMove);
function randomMove(e:Event) {
     speedX += Math.random() * clipSpeed - clipSpeed / 2;
    speedY += Math.random() * clipSpeed - clipSpeed / 2;
    if (clipArray[i].x + speedX > upperLeftLimit.x && clipArray[i].x + speedX < bottomRightLimit.x)
       { clipArray[i].x += speedX;}
  else
        {speedX = 0}
    if (clipArray[i].y + speedY > upperLeftLimit.y && clipArray[i].y + speedY < bottomRightLimit.y)
        {clipArray[i].y += speedY;}
    else
        {speedY = 0}
Thanks

then one or more of your clips are starting outside your limits.  and, you probably don't want to use that code because all the clips move the same amount each loop. 
try:
var clipSpeed:Number=1;
var speedX:Number=0;
var speedY:Number=0;
var upperLeftLimit:Point=new Point(0,0);
var bottomRightLimit:Point=new Point(300,300);
var clipArray:Array=[clip,clip1,clip2];
for(var i:int=0;i<clipArray.length;i++){
    clipArray[i].speedX = speedX;
    clipArray[i].speedY = speedY;
this.addEventListener(Event.ENTER_FRAME,randomMove);
function randomMove(e:Event) {
    for(var i:int=0;i<clipArray.length;i++){
    var mc:MovieClip=clipArray[i];
    mc.speedX+=Math.random()*clipSpeed-clipSpeed/2;
    mc.speedY+=Math.random()*clipSpeed-clipSpeed/2;
    if (mc.x+mc.speedX>upperLeftLimit.x&&mc.x+mc.speedX<bottomRightLimit.x) {
        mc.x+=mc.speedX;
    } else {
        mc.speedX=0;
    if (mc.y+mc.speedY>upperLeftLimit.y&&mc.y+mc.speedY<bottomRightLimit.y) {
        mc.y+=mc.speedY;
    } else {
        mc.speedY=0;
