How can I reference "score" in one script and then use it in another?

Hi, beginner coder here and I’m working on a script for a breakout like game and I’m currently working on the score… However I have hit a brick wall and I cannot seem to fix it. Firstly, I apparently haven’t referenced “score” In my GameManager script, although I think I have. Would appreciate any help, thanks in advance!

(Brick Script)

`using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class brick : MonoBehaviour
{
    public GameManager GM;
    public AudioSource Block_Destroy;
    private int block_health = 1;
    private int score_multiplier = 1;
	void Start (){
        GM = GameObject.FindWithTag("GameManager").GetComponent<GameManager>();
        switch (gameObject.tag)
        {
            case "Purple":
                block_health = 1;
                score_multiplier = 1;
                break;
            case "Blue":
                block_health = 1;
                score_multiplier = 1;
                break;
            case "Yellow":
                block_health = 2;
                score_multiplier = 2;
                break;
            case "Green":
                block_health = 2;
                score_multiplier = 2;
                break;
        }
	}

void Update ()
{

}

void OnCollisionEnter2D(Collision2D col){
    if (col.gameObject.tag == "Ball"){
        Block_Destroy.Play(); 
        block_health--;
    }
    if (block_health <= 0){

       GM.scoreText += 1 * score_multiplier;
        Destroy(gameObject);
    }

	}
}`

(GameManager Script)

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

public class GameManager : MonoBehaviour 
{

    public Text score_count;
    public Text lives_count;

    static public int score = 0;
    static public int lives = 3;
	

    void start ()
	{
	}

    void update()
    {

        score_count.text = score.ToString();
        lives_count.text = lives.ToString();

    }
}

I don’t see any scoreText in the GameManager that you are referncing in the OnTriggerEnter. Since you made it static, you have to access score trough GameManager.score = 1 * score_multiplier; (btw 1 * whatever is always just whatever so no reason to multiply it by 1)
