Once a timer is at 40 go to the next frame.

Question

Hey there,
When a timer in my game hits 40 I want it to go to the next frame. Here is what I have:
onClipEvent (enterFrame) {
          var atFrame:Boolean = false;
          if (_root.timer == 40) {
                    atFrame = true;
          } else {
                    _root.timer++;
          if (atFrame == true) {
                    myRandom = random(3);
                    if (myRandom == 0) {
                              gotoAndStop("game1");
                    if (myRandom == 1) {
                              gotoAndStop("game2");
                    if (myRandom == 2) {
                              gotoAndStop("game3");
Where "game1-3" are the names of my frames. And timer is the name of my dynamicText.
Any suggestions as to why this isn't working would be greatly appreciated.
Kind Regards, Eric

Answer 1

first of all your variable must be initiated
_root.timer=0
Yor code is insede a MovieClip?
I change the code
_root.timer = 0;
onClipEvent (enterFrame) {
          var atFrame:Boolean = false;
          if (++_root.timer == 40) {
                    goGame();
function goGame() {
     myRandom = int(Math.random()*3);
      if (myRandom == 0) {
          _root.gotoAndStop("game1");
     if (myRandom == 1) {
          _root.gotoAndStop("game2");
     if (myRandom == 2) {
          _root.gotoAndStop("game3");
