How to set values for a variable from a different script?

I have some code that I made in unity for a game of mine and I am trying to make a variable change from a different script. I am using java and yes I am also using GetComponent for this but when I try to run my code all i get is an error saying Assets/ScriptController.js(30,72): BCE0034: Expressions in statements must only be executed for their side-effects. This is my code that I made. I will post both scripts:

1. SpinnerNumGen.js

     public var number : int;
        public static var timesClicked : int;
         
        function Update() {
       
        }
        
        function numGen() {
            number = Random.Range(1, 7);
        }
         
        function OnGUI(){
        
        if(GUI.Button(Rect(20,40,80,20), "Roll")){timesClicked++; numGen();}
        
        
        GUI.Label(Rect(10,10,100,30), "You Rolled a: " + number);
        }
   
   

2. ScriptController.js

   function Start() {

   //Button is clicked 3 times

   if (SpinnerNumGen.timesClicked == 3){ script = GetComponent(SpinnerNumGen); script.enabled = false; }

   //Button clicked less than 3 times

   else{ script = GetComponent(SpinnerNumGen); script.enabled = true; }

   //Display timesClicked in console

   Debug.Log(SpinnerNumGen.timesClicked); }

   //Called after button clicked 3 times

   function waitTime(){ yield WaitForSeconds (5);

     script = GetComponent(SpinnerNumGen);
        script.enabled = true;
        
        //Error Below
   
        if(SpinnerNumGen.timesClicked == 3){SpinnerNumGen.timesClicked == 0;}
   
        //Error Above
    }
    
    function Update () {
     waitTime();
     Start();
    }
   
   
   

Basically what I'm trying to do is reset the timesClicked variable to 0 when WaitForTime is completed so that the if statement in the start command can be ran again. P.s. I am sorry for I am a noob venturing into the lands of coding.
