Burg Zerg Arcade Tutorial Help

I am on number 6 tutorial for burgzerg arcade. and here is error: 31,22: A namespace can only contain types and namespace declarations. Here is the script.

 using UnityEngine;

using System.Collections;

public class PlayerAttack : MonoBehaviour { public GameObject target; public float attackTimer; public float coolDown;

// Use this for initialization void Start () { attackTimer = 0; coolDown = 2.0f; }

// Update is called once per frame void Update () { if(attackTimer > 0) attackTimer -= Time.deltaTime;

if(attackTimer < 0) attackTimer = 0;

if(Input.GetKeyUp(KeyCode.F)) { if(attackTimer == 0) Attack(); attackTimer = coolDown; } }

}

private void Attack() { float distance = Vector3.Distance(target.transform.position, transform.position);

Vector3 dir = (target.transform.position - transform.position).normalized;

float direction = Vector3.Dot(dir, transform.forward);

Debug.Log(direction);

if(distance < 2) { if(direction > 0) { EnemyHealth eh = (EnemyHealth)target.GetComponent("EnemyHealth"); eh.AddjustCurrentHealth(-10); } }

}

Its on private void Attack() { I get the error. Any suggestions?
