i wrote this code to make my plane fire bullet but it doesn’t work…

using UnityEngine;
    using System.Collections;
    
    public class shoot : MonoBehaviour {
    
    	public GameObject bulletPrefab;
    	public float speed=5;
    
    	// Use this for initialization
    	void Start () {
    	
    	}
    	
    	// Update is called once per frame
    	void Update () {
    
    		if(Input.GetButtonDown("Junp"))
    			{
    				Instantiate(bulletPrefab,transform.position,transform.rotation);
    				transform.Translate(speed*Time.deltaTime,0,0);
    			}
    	}
    }

if(Input.GetButtonDown(“Junp”))
{
Instantiate(bulletPrefab,transform.position,transform.rotation);
transform.Translate(speed*Time.deltaTime,0,0);
}

should be
if(Input.GetButtonDown("Jump")) { Instantiate(bulletPrefab,transform.position,transform.rotation); transform.Translate(speed*Time.deltaTime,0,0); }

you misspelt jump as junp
