My Debug.Log won't show on the console?

Okay, so i decided that i was going to try and learn about c# in unity, i headed over to the untiy tutorials and i didn't expect to get stuck on the second tutorial. In the tutorial the guy uses this code

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

Upon applying and creating this code myself i realised that my code doesn't work. In the video his code printed the number 5 into the console upon clicking play. In my code nothing happens, does anybody know where i went wrong?
