In UnityScript, why does GUI not get called within hit on collider? - user-interface

Question

I'm trying to print out text when a user touches a sprite, however, even though I get no errors when building and running the code, the code refuses to printout the text and I cannot understand what I am doing wrong. Please help me understand why it does not print.
It prints the debug text when I touch the sprite, but not the GUI text with total.
This is the code:
#pragma strict
function Start () {
OnGUI();
}
function OnGUI(){
//var total = 0;
//GUI.Label( myRect, total.ToString() ); // Displays "10".
//GUI.Label( myRect, "" + bullets ); // Displays "10".
// GUI.Label(Rect(0,0,Screen.width,Screen.height),"Total:"+total);
}
//function Update () {
//}
var platform : RuntimePlatform = Application.platform;
function Update(){
if(platform == RuntimePlatform.Android || platform == RuntimePlatform.IPhonePlayer){
if(Input.touchCount > 0) {
if(Input.GetTouch(0).phase == TouchPhase.Began){
checkTouch(Input.GetTouch(0).position);
}
}
}else if(platform == RuntimePlatform.WindowsEditor){
if(Input.GetMouseButtonDown(0)) {
checkTouch(Input.mousePosition);
}
}
}
function checkTouch(pos){
var total = 0;
var wp : Vector3 = Camera.main.ScreenToWorldPoint(pos);
var touchPos : Vector2 = new Vector2(wp.x, wp.y);
var hit = Physics2D.OverlapPoint(touchPos);
if(hit){
GUI.Label(Rect(0,0,Screen.width,Screen.height),"Total:");
Debug.Log(hit.transform.gameObject.name);
hit.transform.gameObject.SendMessage('Clicked',0,SendMessageOptions.DontRequireReceiver);
//total = total +1;
}
}

You cannot put a gui item outside the OnGUI Method. You need to set a boolean to turn on the label.
Something along these lines.
OnGUI(){
if(labelbool)
GUI.Label ....
}
check(){
labelbool = true;
}
