My Script Won't Update

here i am once again. So i am following the unity tutorial about variable and functions and my script doesn't do what i have told it to do, for example i start with this

 using UnityEngine;
 using System.Collections;
 
 public class VariablesAndFunctions : MonoBehaviour 
 {
     int myInt = 5;
 
         void Start (){
         Debug.Log (myInt);
 
     }

} And it works! It prints my int into the console (5)

But then when i update the script to make it multiply myInt by 2 it doesn't it still types 5 into the console, here's the script

 using UnityEngine;
 using System.Collections;
 
 public class VariablesAndFunctions : MonoBehaviour 
 {
     int myInt = 5;
 
         void Start (){
         Debug.Log (myInt * 2);
 
     }
 }

What am i doing wrong? If anything
