can't declare a variable, help!

Help what’s wrong here!

using UnityEngine;

public class Shooter : MonoBehaviour

public AudioClip Shot;

{
    void Update ( )
    {... etc

You must declare variables inside the class, not in the script declaration! Like this:

using UnityEngine;

public class Shooter : MonoBehaviour {

    public AudioClip Shot; // declare variable inside the class

    void Update ( )
    {
    ...
