i am getting the error.cs0246

please help me i don’t know why i am getting an error

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

public class Destroy : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{

}

// Update is called once per frame
void Update()
{
    
}
private void OnCollisionEnter(Collison collison)
{
    if(collision.gameObject.tag == "Enemy")
    {
        Destroy(this.gameObject);
    }
}

}

There is a typo, collision is missing an i.

private void OnCollisionEnter(Collision collision)

@TheTrueDuck thanks for the help with the error i fixed that but when my sprite hits the enemy it wont disappear do you know why?
