Script not getting called, even when attached to GameObject

I’m trying to run a leaderboard script, but the script itself is not getting called. I’ve done the debugs under void update, and there are no logs in the console. I double-checked to make sure that it was attached to a GameObject in the scene, and it was. I tried adding to every single possible GameObject in the scene, yet it was still not getting called. Are there any errors in the script itself? Or is it a problem with the scene?

Scene: Imgur: The magic of the Internet

Script (note that it isn’t complete yet):

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Leaderboard : MonoBehaviour {

private Transform entryContainer;
private Transform entryTemplate;

private void Awake ()
{

    entryContainer = transform.Find("highscoreEntryContainer");
    entryTemplate = entryContainer.Find("highscoreEntryTemplate");
    entryTemplate.gameObject.SetActive(false);

    float TemplateHeight = 20f;

    for (int i = 0; i < 20; i++)
    {
        
        Transform entryTransform = Instantiate(entryTemplate, entryContainer);
        RectTransform entryRectTransform = entryTransform.GetComponent<RectTransform>();
        entryRectTransform.anchoredPosition = new Vector2(0, -TemplateHeight * i);
        entryTransform.gameObject.SetActive(true);

        int rank = i + 1;

        string rankString;
        switch (rank)
        {

            default:
                rankString = rank + "TH"; break;

            case 1: rankString = "1ST"; break;
            case 2: rankString = "2ND"; break;
            case 3: rankString = "3RD"; break;
        }

        entryTransform.Find("Pos").GetComponent<Text>().text = "";
        entryTransform.Find("Name").GetComponent<Text>().text = "";
        entryTransform.Find("Score").GetComponent<Text>().text = "";

        int score = Random.Range(0, 10000);

        entryTransform.Find("scoreText").GetComponent<Text>().text = score.ToString();

        string name = "AAA";
        entryTransform.Find("nameText").GetComponent<Text>().text = name;

    }

    

}

// Use this for initialization
void Start () {
	
}

// Update is called once per frame
void Update () {

    Debug.Log("E");

}

}

Check the console. You are getting a NullRef exception.
This is probably happening in your Awake() and thus stops exectution before your Update() method is called.
