Both players take damage when hit?,both players take damage

Hello i'm new to unity and am working on a little 2d fighting game but i have a little problem. i already have health bars for the 2 players but the problem is every time TakeDamage() is called, both charackters take damage. Here is the essential code so far, both have diffrent scipts but nearly the same context:

 public Image HealthBar;
 public float health= 100;
 
 public void TakeDamagel (float amount){
         health -= amount;
 
         HealthBar.fillAmount = health/ 100f;
         if(health <= 0)
         {
             Die();
         }
     }
 
     void OnTriggerEnter2D (Collider2D other){
 
 
         if (other.gameObject.name.Equals("Colm")){
             TakeDamagel(10);
         }
     }
 
     void Die(){
         anim.SetBool ("isWalking", false);
         anim.SetTrigger ("Die");
     }
 }
