(C#) My enemy dosent take damage ScriptFix

public class DestroyScript : MonoBehaviour {

public float lifetime = 1.0f;

 void Start ()        
 {
 }
 void Update () {
 }
 void Awake ()
 {
     Destroy (gameObject,lifetime);
 }
 void OnTriggerEnter(Collider other)
 {
     if(other.gameObject.tag == "Enemy")
     {
     //other.gameObject.GetComponent<>().EnemyCurHealth = EnemyCurHealth - 30;
         DestroyObject(other.gameObject);
         Destroy(gameObject);
     }
 }
 

}

I think the problem is on the "//" line cuz im getting errors all the time and i dont know what it is i need in it. i know i need GetComponent to get the health script (The health is just an int) and after i need an

if(EnemyCurHealth = 0)

{

Destroy(gameObject);

}

But can anyone see what i need to do befor?

EDIT: //other.gameObject.GetComponent().EnemyCurHealth = EnemyCurHealth - 30; as a <>script but it wont show in the question somehow
