What is wrong with my code...watched an unity tutorial and I keep forgetting everything!

I think I fixed it a bit btw but now it will only say "INCORRECT" in the console

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 
 
 public class LightSwitch : MonoBehaviour {
     private int disVar;
 
     void Awake () {int disVar = Plus2 (6, 7);
         Debug.Log (disVar);}
 
     public Light myLight;
 
     int Plus2 (int di1, int di2) {int returnValue = di1 * di2;
         return returnValue;}
 
 
     void Update() {if (disVar == 42) {
             Debug.Log("CORRECT");
         }
     
                 else {Debug.Log("INCORRECT");}}
 
 
 }
