having problems converting this script to android

hi, i am working on an android racing game, the car script works fine but i have a camera script that swithces between first and third person views. i have one gui texture button that is supposed to switch cameras. the original script was to switch cameras on tab.

original:

 var FirstPerson : Camera;
 var ThirdPerson : Camera;
 
 
 var Active : boolean = true;
 
 function Start(){
    FirstPerson.enabled = true;
    ThirdPerson.enabled = false;
    
    
    
 }
 
 function Update(){
 
     
 if(Input.GetButton("Tab") && Active == false)
 {
    FirstPerson.enabled = false;
    ThirdPerson.enabled = true;
    
    
    
    Active = true;
 }
 else if(Input.GetButton("Tab") && Active == true)
 {
    FirstPerson.enabled = true;
    ThirdPerson.enabled = false;
    
    
    
    Active = false;
 }
 }
 

what im working on:

 var FirstPerson : Camera;
 var ThirdPerson : Camera;
 var camControl : GUITexture;
 
 
 var Active : boolean = true;
 
 function Start(){
    FirstPerson.enabled = true;
    ThirdPerson.enabled = false;
    
    
    
 }
 
 function Awake(){
 camControl = GameObject.Find("Cameraicon").guiTexture;
 }
 
 
 function Update(){
 
 if (Input.touchCount > 0) {
 
 for (var touch : Touch in Input.touches) && Active == false
     {
         if (camControl.HitTest (touch.position)) ;
         FirstPerson.enabled = false;
         ThirdPerson.enabled = true; 
 //if(Input.GetButton("Tab") && Active == false)
 //{
    //FirstPerson.enabled = false;
   // ThirdPerson.enabled = true;
    
    
    
    Active = true;
 }
 
 }
 
 else if (Input.touchCount > 0) {
 
 for (var touch : Touch in Input.touches) && Active == true 
     {
         if (camControl.HitTest (touch.position)) ;
         FirstPerson.enabled = true;
         ThirdPerson.enabled = false; 
 //else if(Input.GetButton("Tab") && Active == true)
 //{
    //FirstPerson.enabled = true;
    //ThirdPerson.enabled = false;
    
    
    
    Active = false;
 }}
 }
