Referencing scoreManager when instantiating a player

I am wokring on a game where a player has to go through an enemy to score a point. But I am struggling to make the score count work. I am watching tutorials and trying various ways but something isnt working so I hope someone can help me here.

I have a player prefab, which gets instantiated when I press play in Unity. Then I have enemies spawning and when a player goes though one, the score should go to 1..and so on.

I have a gameObject in the scene with score script attached

public class Score : MonoBehaviour
{
    public Text scoreText;
    int score;
    // Start is called before the first frame update
    void Start()
    {
        score = 0;
    }

    public void ScoreUp()
    {
        score++;
        scoreText.text = score.ToString();
    }
}

Then I have a player script attached to a player prefab

public class PlayerController : MonoBehaviour
{
    private Score score; //Reference to Score script

    private void Start()
    {
        score = GameObject.FindWithTag("ReferenceManager").GetComponent<Score>();
    }

    private void Update()
    {
       if (Input.GetMouseButtonDown(0))
        {
            //movement code
        }
    }

    public void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Enemy"))
        {
            score.ScoreUp();
            Debug.Log("HIT");
        }
    }
}

Reference manager tag is the gameObject in the scene with score script. If someone could help me with this problem would be really awesome. Thank you

Apparently my score collider which is attached to enemy doesnt work.

I tried the same thing but with trigger collider on its own and the score count works perfectly. So I will play around and try to figure out the correct place for that trigger collider. Thank you whoever tried to help me! :)

UPDATE:

I had two scripts attached to scoreManager, and when i removed the other script, the score count started to work. Actually not sure why 2 scripts were conflicting but this fixed the problem.

Define a gameobject variable so you can attach the score object to it in the editor

public class PlayerController : MonoBehaviour
{
    [SerializeField]
    public GameObject score_object;//This will allow u to select the player controller game object and set the variable to the score game object. The score game object is where the data will be stored.
    private Score score;

    private void Start()
    {
        score = score_object.GetComponent<Score>();
    }

    private void Update()
    {
       if (Input.GetMouseButtonDown(0))
        {
            //movement code
        }
    }

    public void OnTriggerEnter2D(Collider2D collision)
    {
        if (collision.CompareTag("Enemy"))
        {
            score.ScoreUp();
            Debug.Log("HIT");
        }
    }
}

I have never tried using the tag manager, What i suspect is that may be where your problem lies. Just try instancing it like this and see what happens.
