Simple Points Code

I’m just trying to have the thePoints int increase by one when the OnTriggerEnter event is completed. Can someone let me know where I went wrong, or what kind of code I need?

Thanks

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

public class Collection : MonoBehaviour
{ public GameObject other;
    public GameObject block;
    public int thePoints = 0;


    // Start is called before the first frame update
    void Start()
    {
        block.SetActive(false);

    }

    // Update is called once per frame
    void Update()
    {
        string scoreMessage = "Pieces = ";
        print(scoreMessage);
    }

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.name == "screw")
        {
            thePoints++;
            block.SetActive(true);
        }
    }
        }

I got the code to work. Thank you regardless
