unity 2 object spawn on button click

I'm trying to make a grenade throwing script but when i test it, it always spawn 2 grenade at the same time.

public class GrenadeThrow : MonoBehaviour {
    public GameObject bulletprefab;
    float speed =20f;
    // Use this for initialization
    void Start () { }

    // Update is called once per frame
    void Update () {
        if (Input.GetButtonUp("Fire1"))
        {
            Camera cam = Camera.main;
            GameObject Grenade = Instantiate(bulletprefab, cam.transform.position + cam.transform.forward, cam.transform.rotation);
            Grenade.GetComponent<Rigidbody>().AddForce(cam.transform.forward * speed, ForceMode.Impulse);
        }
    }
}

First of all, Input.GetButtonDown is more appropriate for this than Input.GetButtonUp. You can try it and see if Input.GetButtonDown is still what you want.

when i test it, it always spawn 2 grenade at the same time

Assuming that this is the actual code you are using to spawn and throw Objects, then it should work fine.

There two likely problems:

1.The GrenadeThrow script is likely attached to the-same GameObject multiple times.

2.The problem is likely to be that you have your GrenadeThrow script attached to multiple GameObjects. It should only be attached to one GameObject.
