Why is OnGUI not working?

OnGui in not working if I have the Hover function updated in Update. The print shows that showLabel is changing from false to true as I hover over the object but the label will not come up. Here are the two scripts that are talking to each-other:

Interactee.js

 var Interactable : boolean = true;
 
 private var showLabel : boolean;
 
 function Update(){
     print (showLabel);
     Hovers(false);
 }
 
 //Is the player interacting with the this object???
 function Interact(Interacting : boolean){
     if (Interactable){
         if (Interacting){
             //Action();
         }
     }
 }
 
 function Hovers (Hovering : boolean){
     if(Hovering){
         showLabel = true;
     }else{
         showLabel = false;
     }
 }
 
 //The Action you want to happen...
 /*function Action(){
     //Make the item a child of backpack...
     this.transform.parent = backpack.transform;
 }*/
 
 //While hovered show something...
 function OnGUI(){
     if (showLabel){
         GUI.Label (Rect (Screen.width*0.5,Screen.height*0.65,100,50), "Hovering");
     }
 }
 

Interactor.js

 var distance = 10;
 var Interacting : boolean = true;
 var Hovering : boolean = true;
 
 //When "Interact" button is pressed do function Interact... 
 function Update(){
     Hover();
     if (Input.GetButtonDown("Interact")){
         Interact();
     }
 }
 
 //Raycast
 function Interact(){
     var hit : RaycastHit;
     var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 20));
     
     if (Physics.Raycast (ray, hit, distance)){
         hit.transform.SendMessage("Interact", Interacting, SendMessageOptions.DontRequireReceiver);
     }
 }
 
 //Raycast
 function Hover(){
     var hit : RaycastHit;
     var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 20));
     
     if (Physics.Raycast (ray, hit, distance)){
         hit.transform.SendMessage("Hovers", Hovering, SendMessageOptions.DontRequireReceiver);
     }
 }
