Can anyone help with me with my attack script and enemy script?

When I attack I'm not sure why the enemy is not taking damage, my enemy script works i believe as when I set its health to 0 the enemy is deleted.

this is the script i believe has problems with it. Thanks

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
  public class AttackScript : MonoBehaviour {
  
      public float hp = 10f;
      public float toTarget;
      public float range = 5f;
      
      // Update is called once per frame
      void Update () {
          Attack ();
      }
      void Attack(){
          RaycastHit hit;
          Vector3 forward = transform.TransformDirection(Vector3.forward);
          Vector3 origin = transform.position;
          if(Physics.Raycast(origin, forward, out hit, range)){
              if(hit.transform.gameObject.tag == "Enemy"){
                  hit.transform.gameObject.SendMessage("TakeDamage", hp);
              }
      
          }
      }
      
  }

Here is my enemy script.

  using System.Collections;
  using System.Collections.Generic;
  using UnityEngine;
  
      public class EnemyScript : MonoBehaviour {
          public int enemyHealth = 50;
          void TakeDamage(int hp){
              enemyHealth -= hp;
          }
      
          // Update is called once per frame
          void Update () {
              if (enemyHealth <= 0) {
                  Destroy (gameObject);
              }
          }
      }
