send message object variable

Hello, I am trying to send a variable with an object (var del = this.Gameobject;) to another script.

What I have is: var hitPoints : float = 50.0; var sound : AudioClip; var del = this.Gameobject;

 function OnTriggerEnter (other : Collider) { 
     if (other.CompareTag ("Player")){
         other.SendMessageUpwards("Medic", hitPoints, SendMessageOptions.DontRequireReceiver);
         other.SendMessageUpwards("Del", del, SendMessageOptions.DontRequireReceiver);
         AudioSource.PlayClipAtPoint(sound, transform.position);
         //Destroy(gameObject);
         //PhotonNetwork.Destroy(this.gameobject);
     }    
 }

for sending the message, and:

 public void Medic (float hitPoints) {
     currentHp+=150;
         
  if (currentHp > 250.0)
     currentHp=250;
     //PhotonNetwork.Destroy(other);
 
 }
     public void Del (GameObject del) {
     PhotonNetwork.Destroy(del);
 }

for receiving The problem is I get this error when running the game:

Failed to call function Del of class PlayerDamage Calling function Del with no parameters but the function requires 1. UnityEngine.Component:SendMessageUpwards(String, Object, SendMessageOptions) Medic:OnTriggerEnter(Collider) (at Assets/Resources/NewScripts/Medic.js:8)

You probably already saw the first script is js and the second c# public void Medic does work correctly, only the Del void gets an error

It would be great if someone could help me
