Moving to the "Results" scene after the player killed all the enemies in the field

Hello there,

I'm making a TPS, and trying to show the "Results" once the player killed all the enemy in the "Main" scene.
I'm using the script below, but nothing happens.

What am I doing wrong? Maybe I stored this script in a wrong place?
(I made a "Scripts" folder in the Project tab)

Any help will be appreciated.

========================================================================

using UnityEngine;
using System.Collections;
using UnityEngine.SceneManagement;

public class GameClearController : MonoBehaviour {


private GameObject[] enemyObjects;

void Update () {


enemyObjects = GameObject.FindGameObjectsWithTag("Enemy");

print(enemyObjects.Length);


if(enemyObjects.Length == 0){


SceneManager.LoadScene("Results");
}
}
}
