my script worked and earlier, now does not work Version 5:34

Hi, I am unsure what to do, because my script worked perfectly earlier, Now to my surprise does not work in new versions: The following script was the following: When the player entered the trigger was asked to put a code and door opened, but in the new version 5.3.4 does not work anymore, I spent a great time to get to this point, I decided to switch to the new version and now I am not able to solve it. here is the script if anyone can help me I will be very grateful. Thank you.

 var close = false;
 var CodigoBau : String = "";
 var stringToEdit : String;
 //var estiloAviso = GUIStyle;  
 
 var AngleX : float = 0.0;
 var AngleY : float = 0.0;
 var AngleZ : float = 0.0;
 
 private var targetValue : float = 0.0;
 private var valorAtual : float = 0.0;
 private var easing : float = 0.002;
 
 var Sound:AudioClip;
 
 var Target : GameObject;
 
 function OnTriggerEnter (other : Collider) {
     targetValue = AngleX;
     currentValue = 0.0;
     GetComponent.<AudioSource>().PlayOneShot(Sound);
 }
 
 function OnTriggerExit (other : Collider) {
     currentValue = AngleX;
     targetValue = 0.0;
     GetComponent.<AudioSource>().PlayOneShot(Sound);
 
 }
 
 
 function SetTheGUI () {
     close = true;
     targetValue = AngleX;
     //valorAtual = 0.0;
 }
 
 function UnSetGUI () {
     close = false;
 
 }
 
 function OnGUI(){
 if (close){
     GUI.Box (Rect(Screen.width/2-60, Screen.height/2-80, 150, 35),"DIGITE O CÓDIGO");
     
     stringToEdit = GUI.TextField (Rect(Screen.width/2-60, Screen.height/2-40, 150, 25),stringToEdit, 11);
 
     
    if(stringToEdit == CodigoBau){
    
     GetComponent.<AudioSource>().PlayOneShot(Sound);
     valorAtual = valorAtual + (targetValue - valorAtual) * easing;
     //GameObject.particleEmitter.emit = true;
      
     Target.transform.rotation = Quaternion.identity;
     Target.transform.Rotate (0 , 0, valorAtual);// este funciona
     //Target.transform.Rotate (0 , valorAtual, 0);//gira no eixo y
     //Target.transform.Rotate (valorAtual, 0 , 0);//gira no eixo z
