Is there a way to tell if the object with a trigger that i am colliding with has a variable and that variable's value?

So, I am making a rhythm game and I need to tell if the object, whose trigger I’m colliding, with has a variable of type float named note and what note’s value is. My idea was that it would be something like (* what I thought):

void OnTriggerEnter2D(Collider2D other)
{
if(other.tag == “Note” && *other.note == currentNote)
{
Destroy(other);
}
}

My entire code is:

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

public class buttonDetector : MonoBehaviour
{
float currentNote;
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
    CheckButtonsDown();
    CheckButtonsUp();
}

void CheckButtonsDown()
{
    if(Input.GetKeyDown(KeyCode.RightArrow))
    {
        Debug.Log("right");
        currentNote += 5;
    }
    if(Input.GetKeyDown(KeyCode.LeftArrow))
    {
        Debug.Log("left");
        currentNote += 50;
    }
    if(Input.GetKeyDown(KeyCode.UpArrow))
    {
        Debug.Log("up");
        currentNote += 500;
    }
    if(Input.GetKeyDown(KeyCode.DownArrow))
    {
        Debug.Log("down");
        currentNote += 5000;
    }
}

void CheckButtonsUp()
{
    if(Input.GetKeyUp(KeyCode.RightArrow))
    {
        Debug.Log("right off");
        currentNote -= 5;
    }
    if(Input.GetKeyUp(KeyCode.LeftArrow))
    {
        Debug.Log("left off");
        currentNote -= 50;
    }
    if(Input.GetKeyUp(KeyCode.UpArrow))
    {
        Debug.Log("up off");
        currentNote -= 500;
    }
    if(Input.GetKeyUp(KeyCode.DownArrow))
    {
        Debug.Log("down off");
        currentNote -= 5000;
    }
}

void OnTriggerEnter2D(Collider2D other)
{
    if(other.tag == "Note" && other.note == currentNote)
    {
        Destroy(other);
    }
}

}

and:

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

public class Obstacles : MonoBehaviour
{
public float speed = 1;

public float note;
// Start is called before the first frame update
void Start()
{
    
}

// Update is called once per frame
void Update()
{
    float speedB = speed * Time.deltaTime;
    transform.Translate(0, -speedB, 0);
}

}

Can anyone solve this, or is there a different way to handle this, keeping in mind I have several objects with the shorter script, and I need this to work individually on all of them.

Please format your code correctly.

Also, use TryGetComponent and try to get an interface that implements the variable you are looking for. If everything you expect to have the variable implements the interface then you can handle that expectation across many objects.
