Unfixable Assets/Scripts/PlayerAttack.cs(30,15): error CS1525: Unexpected symbol `private'

Assets/Scripts/PlayerAttack.cs(30,15): error CS1525: Unexpected symbol `private' Here is my code, which is where my problem is, and it seems impossible to fix, because everything I have tried, from extra curly braces to different tabs.

     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 < 2.5f) {
             if(direction > 0) {
                 EnemyHealth eh = (EnemyHealth)target.GetComponent("EnemyHealth");
                 eh.AddjustCurrentHealth(-10);
                     }
                 }
             }
         }
