Multiple inexplicable errors

Unity Engine
1 
using UnityEngine;
using System.Collections;

public class StunGun : MonoBehaviour {
	private Rigidbody curShot;
	public Rigidbody shotPre;
	public Transform shooter;
	public float speed = 60.0f;

	// Use this for initialization
	void Start () {
		
	}
	
	// Update is called once per frame
	void Update () {
	`	if (Input.GetButton("Fire1")) {
			Charge();
		}
	}
	
	private void Charge () {
		if (!curShot) {
			curShot = (Rigidbody)Instantiate(shotPre, shooter.position, shooter.rotation);
		}
		
		curShot.transform.position = shooter.position;
		curShot.transform.rotation = shooter.rotation;
		
		if (Input.GetButtonUp("Fire1")) {
			StartCoroutine(Shoot());
		}
	}
	
	private IEnumerator Shoot () {
		if (curShot) {
			curShot.velocity = shooter.transform.TransformDirection(speed, 0, 0);
		}
		
		yield return new WaitForSeconds(2);
		
		curShot = null;
	}
}

in that code i get these errors, why?

void Update () {
	`	if (Input.GetButton("Fire1")) {

Just below Update() on the left of your if statement you’ve got a funky little character :wink:
