InvokeRepeating doesn't work

Unity Engine
1

I’m trying to call the method SpawnRandom() every 3 second (starting from 1 second). When i press play the method doesn’t get called

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

public class GameManager2 : MonoBehaviour
{
    public static float loweBound = -7.4f;
    public static float upperBound = 8.4f;
    public bool gameover = false;
    public TextMeshProUGUI gameov;
    public Button RestartB;
    public Button PauseB;
    public Button ResumeB;
  
    public GameObject[] prefab;
   
    public float spawnX = 13.8F;
    public float spawnYuP = 7.7F;
    public float spawnYdW = -6.34F;
    public float initial = 1.0f;
    public float finale = 3.0f;

   

  
    void start()
    {
        InvokeRepeating("SpawnRandom", initial, finale);
    }

  
    void Update()
    {
      
    }


public void SpawnRandom()
    {
        float rand = UnityEngine.Random.Range(spawnYdW, spawnYuP);
        Vector3 v = new Vector3(spawnX, rand, 0);
        Instantiate(prefab[0], v, prefab[0].transform.rotation);
        Debug.Log("test call");
    }

The Unity message ‘Start’ has a capital S.

Even with the start method written correctly the problem is still there

Make sure your variables are set to values you expect in the inspector (i.e. not 0). Although you have values in the code, these will be overridden by whatever is in the inspector since these are public. Also, make sure your script is actually attached to a gameobject, I think I speak for all of us when I say we have all made such a mistake at least once.
