Missing movie clip

Question

Hi.  I have six movie clips positioned across the stage and a following row of six movie clips below it. All of them move up the stage and are activated with a seperate key press and it works ok first time.  The following times going up the stage, the fith and sixth movie clips are not visible on the first row, but are on the second row.  Why and what can I do to fix it?  The following code is what I am using for each clip - just repeated and named accordingly.       
CODE:  addEventListener(Event.ENTER_FRAME, leftbubbleMove);
function leftbubbleMove(e:Event):void {   
    if (leftbubble_mc.y > - 150) {
        trace(leftbubble_mc.y);
        leftbubble_mc.y -=2;
    } else {
        leftbubble_mc.y = 650
        leftbubble_mc.gotoAndStop(1);       
        //leftbubble has reached the top
        //trace("leftbubble has burst");
        //leftbubble_mc.gotoAndPlay(2);
        //leftbubble_mc.y < 50;
    //code to change the color of a movieClip
    var myColor:ColorTransform = leftbubble_mc.transform.colorTransform;
    myColor.color = 0x00FFFF;
    //detect when bubble has entered the target zone
    if (leftbubble_mc.y < 100 && leftbubble_mc.y > 50) {
        //code in here changes the left bubble when it
        //enters the target zone.
        //change back to original when gone past target zone.
        trace("color change bubble");
        leftbubble_mc.transform.colorTransform = myColor;
        //leftbubble_mc.color = 0x00FFFF;
    } else {
        myColor.color = 0xFFFF99
        leftbubble_mc.transform.colorTransform = myColor;
    //detect when bubble has left the target zone   
addEventListener(Event.ENTER_FRAME, leftbubbleaMove);
function leftbubbleaMove(e:Event):void {   
    if (leftbubblea_mc.y > - 150) {
        trace(leftbubblea_mc.y);
        leftbubblea_mc.y -=2;
    } else {
        leftbubblea_mc.y = 650
        leftbubblea_mc.gotoAndStop(1);       
        //leftbubblea has reached the top
        //trace("leftbubblea has burst");
        //leftbubblea_mc.gotoAndPlay(2);
        //leftbubblea_mc.y < 50;
    //code to change the color of a movieClip
    var myColor:ColorTransform = leftbubblea_mc.transform.colorTransform;
    myColor.color = 0x00FFFF;
    //detect when bubble has entered the target zone
    if (leftbubblea_mc.y < 100 && leftbubblea_mc.y > 50) {
        //code in here changes the leftbubblea when it
        //enters the target zone.
        //change back to original when gone past target zone.
        trace("color change bubble");
        leftbubblea_mc.transform.colorTransform = myColor;
        //leftbubblea_mc.color = 0x00FFFF;
    } else {
        myColor.color = 0xFFFF99
        leftbubblea_mc.transform.colorTransform = myColor;
    //detect when bubble has left the target zone   
AND ALSO
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler );
function keyDownHandler(e:KeyboardEvent):void {
        if (e.keyCode == "Q".charCodeAt()) {
        trace("Q has been pressed");
    //place if to limit region of screen in which bubble can be popped here
    //removeChild(leftbubble_mc)
        if (leftbubble_mc.y < 100 && leftbubble_mc.y > 70)  {
        trace("leftbubble has been burst"); 
        leftbubble_mc.gotoAndPlay(2); 
        if (e.keyCode == "Q".charCodeAt()) {
        trace("Q has been pressed");
    //place if to limit region of screen in which bubble can be popped here
    //removeChild(leftbubble_mc)
        if (leftbubblea_mc.y < 100 && leftbubblea_mc.y > 70)  {
        trace("leftbubblea has been burst");
        leftbubblea_mc.gotoAndPlay(2);
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler ); 
        if (e.keyCode == "G".charCodeAt()) {
        trace("G has been pressed");
    //place if to limit region of screen in which bubble can be popped here
    //removeChild(left1bubble_mc)
        if (left1bubble_mc.y < 100 && left1bubble_mc.y > 70)  {
        trace("left1bubble has been burst");
        left1bubble_mc.gotoAndPlay(2);

Answer 1

Please ignore this question -  I had
code typing errors.  Got it working.
