Error 1151 in a reaction timer

Question

i have been working on a reaction timer and i need to run the same program multiple times but put in different colored squares (when the square shows up click stop to get time) to see if that effected the reaction time so i made a bunch of seperate files with the different colors but i wanted to combine them and after i combined them i had a bunch of duplicates and i got those fixed but i still have error 1151.
i have the same text thirty times and where the numbers and myy is they are to get rid of duplicate terms
var blueSquare=new blueSquare();
timeline 1
stop();
var myy1Timer = new Timer(2500);
myy1Timer.addEventListener(TimerEvent.TIMER, blueSquareDelay1);
myy1Timer.start();
var blueSquare = new blueSquare();
trace (blueSquare);
function blueSquareDelay1(E: TimerEvent):void{
addChild(blueSquare);
blueSquare.x = 270;
blueSquare.y = 200;
timeline 2
stop();
//1.
myText_txt.text = "0";
trace(myText_txt);
var myTimer2  = new Timer(30,0);
myTimer2.addEventListener(TimerEvent.TIMER, stopWatch1);
//2.
function stopWatch1(event:TimerEvent):void {
myText_txt.text=String(myTimer2.currentCount);
//3.
stop_btn.addEventListener(MouseEvent.CLICK, stopClock1);
reset_btn.addEventListener(MouseEvent.CLICK, resetClock1);
//4.
myTimer2.start();
//5.
function stopClock1(event:MouseEvent):void {
myTimer2.stop();
//6.
function resetClock1(event:MouseEvent):void {
myTimer2.reset(myText_txt.text="0");
if you are planning on building it to test i have three buttons the stop start and reset with the instances stop_btn etc. then there is an adaptive text box with instance of myText_txt i also have not put time in to get the start and reset buttons working it just starts on its own

Answer 1

i am having a blank and have no idea what the class would be in this case but i did go trough and replace everything with the new code section that you gave me including everything like the actionscript export code and all the other stuff and it still wasnt working (probobly because of something with the class as you said)
i also noticed that in the error reports it doesnt report the first error untill frame three where frame one is the "menu"
and two is the first reaction thing. so the first occurence doesnt have an error in it.
i also failed to mention in my first post that it worked when the one program was by itself and didnt stop untill i put all thirty repititions into the same program
thanks
