Change Parameters to script with other script

I have a boss with two script in different parts. When i put the health in 10 i need to change the velocity of the boss to 4. I write the script but doesn't work.

The first script:

 public class VitalPoint : MonoBehaviour
 {
     public int health = 12;
     private gameMaster gm;
     private UnityEngine.Object explosionRef;
     public GameObject Hiedra;
 
     public bool isHurt = false;
 
     private HiedraScript ChangeVelocity;
 
 
     void Start()
     {
         gm = GameObject.FindGameObjectWithTag("GameMaster").GetComponent<gameMaster>();
         explosionRef = Resources.Load("Explosion");
         ChangeVelocity = gameObject.GetComponent<HiedraScript>();
     }
 
     void Update()
     {
         
     }
 
     void OnTriggerEnter2D(Collider2D collision)
     {
         if (collision.CompareTag("Bullet"))
         {
             Destroy(collision.gameObject);
 
             health--;
 
             Hiedra.GetComponent<Animation>().Play("Player_RedFlash");
 
             if (health <= 10)
                 MovesFaster();
                 isHurt = true;
                 
 
             if (health <= 0)
                 KillSelf();
         }
         if (health <= 0)
         {
             gm.points += 20;
         }
     }
 
     private void MovesFaster()
     {
         ChangeVelocity.moveSpeed = 4f;
     }
 
     private void KillSelf()
     {
         GameObject explosion = (GameObject)Instantiate(explosionRef);
         explosion.transform.position = new Vector3(transform.position.x, transform.position.y + 2f, transform.position.z);
         Destroy(GameObject.Find("Hiedra"));
     }
 }

The parameter of boss script:
