Start and Update dont work and checkmark for enabling/disabling script has disappeard

when i hit play in unity, i noticed that the bullets didn’t move. I looked at the variables from the inspector and they are still 0, even though in the other scrip they are 20. I changed the values from 0 to 20 manually for testing but they are still not moving. Then i also noticed that there is no checkmark for enabling or disabling. WTF is going on?! Here’s my scipt:

using UnityEngine;

public class BulletInfo : MonoBehaviour {

	public int Damage, Speed;
	public WeaponInfo Currentweapon;
	//WeaponInfo is a script's name
	public GameObject Camera;

	void start()
	{ 
		//Get the Damage and speed that's already defined in the other script
		Damage = Currentweapon.Damage;
		Speed = Currentweapon.BulletSpeed;
	}
	void update()
	{
		//Move the bullet towards where the camera is facing
		gameObject.GetComponent<Rigidbody>().AddForce(Camera.transform.forward * Speed);
	}

you making the spelling mistake: correct the spelling “Start” and “Update” like this
