The value of the label component does not show

I have already created a button function early in my code for it to be clicked. These functions that I am showing to you gets value of total, lowest and highest value from the array. What I wanted to do is to put those values in my label, so that when I test it in the movie, they will appear.

Here is my entire code:

// This line makes the button, btnaddScore wait for a mouse click

// When the button is clicked, the addScore function is  called

btnaddScore.addEventListener(MouseEvent.CLICK, addScore);

// This line makes the textinput wait for a mouse click

// When this component is clicked, the clearLabels function is called

txtinScore.addEventListener(MouseEvent.CLICK, clearLabels);

// This line makes the button, btnDisplay wait for a mouse click

// When the button is clicked, the golfscores function is called

btnDisplay.addEventListener(MouseEvent.CLICK, golfscores);

// declare the global variables

var holeNumber:Number = 0; // array of holeNumber

var golfScore:Array = new Array(); // array of golf scores

var HoleNumber:Array = new Array(); // array of golf numbers

// This is the addScore function

// e:MouseEvent is the click event experienced by the button

// void indicates that the function does not return a value

function addScore(e:MouseEvent):void

{

// declare the variables

var Score:String; // score for each golf holes entered by the usert

Score = txtinScore.text; // get the score from the user

HoleNumber.push(Score); // append the number to the end of the array

golfScore.push(Score); // append the score to the end of the array

lblPrompt2.text = "Number of Golf Scores Entered: " + golfScore.length; // display the length of the array in the label

// sets the user to enter scores only up to 18 golf holes

holeNumber++;

if (holeNumber <= 17)

{

lblPrompt1.text = "Enter the score for hole #" + String(HoleNumber.length + 1) + ":";

}

else

{

lblPrompt1.text = "All scores are entered.";

txtinScore.text = "";

btnaddScore.enabled = false;

}

}

// This is the clearLabels function

// e:MouseEvent is the click event experienced by the textInput

// void indicates that the function does not return a value

function clearLabels(e:MouseEvent):void

{

txtinScore.text = "";

}

// This is the golfscores function

// e:MouseEvent is the click event experienced by the button

// void indicates that the function does not return a value

function golfscores(e:MouseEvent):void

{

lblPrompt3.text = "";

for (var x=0; x < golfScore.length; x++)

{

lblPrompt3.text += golfScore + "\r";

}

}

// This is the totalScore function

// golfScore array of numbers

// returns the total value in the array

function totalScore(golfScore):Number

{

var y:Number = 0;

for (var z:int=0; z<golfScore.length; z++)

{

y += golfScore;

lbltotalScore.text = "Total:" + golfScore;

}

return y;

}

// This is the lowestScore function

// golfScore array of numbers

// returns the lowest value in the array

function lowestScore(golfScore):Number

{

var a:Number = golfScore[0];

for (var b:int=1; b<golfScore.length; b++)

{

if (golfScore < a)

{

a = golfScore;

lblLowestScore.text = "Lowest Score:" + golfScore;

}

}

return y;

}

// This is the highestScore function

// golfScore array of numbers

// returns the highest value in the array

function highestScore(golfScore):Number

{

var c:Number = golfScore[0];

for (var d:int=1; d<golfScore.length; d++)

{

if (golfScore > c)

{

c = golfScore;

lblhighestScore.text = "Highest Score:" + golfScore;

}

}

return c;

}

I am referring to the last 3 functions in my code. Please let me know if I did this right and please let me know any changes I needed to do.
