Console showing damage indicator, but damage multiplication is incorrect.

Hello,

I need my enemy to do 1 damage, trap to do 2 damage, and repair kit to heal 5 damage. My repair kit works fine and heals only when player is below max health and for the correct amount. I copied the same script for my trap and altered a bit to damage the player and when the trigger is activated, player goes from 10 health to 0 instantly.

Here is my trap script:

 private void OnTriggerEnter(Collider other)
 {
     PlayerController controller = other.GetComponent<PlayerController>();

     if (controller != null)
     {
         if (controller.currentHealth > 0)
         {
             controller.ChangeHealth(-2);
             Destroy(gameObject);
             Debug.Log("Player takes 2 damage from damage zone.");
         }
     }
 }

And here is the relevant information from my player controller script:

 public int maxHealth = 10;
 public int currentHealth;

 public float timeInvincible;
 public float invincibleTimer;
 public bool isInvincible = false;    

 void Start()
 {
     playerRb = GetComponent<Rigidbody>();
     currentHealth = maxHealth;
 }

 void Update()
 {
     PlayerMovement();
     LayTrap();

     if (isInvincible)
     {
         invincibleTimer -= Time.deltaTime;
         
         if (invincibleTimer < 0)
         {
             isInvincible = false;
         }
     }
 }

 private void OnCollisionEnter(Collision collision)
 {
     if (collision.gameObject.CompareTag("Enemy"))
     {
         collision.gameObject.GetComponent<EnemyController>().ChangeHealth(-1);
         Debug.Log("Enemy takes 1 damage from player."); 
     }
 }

 public void ChangeHealth(int amount)
 {
     currentHealth = Mathf.Clamp(currentHealth = amount, 0, maxHealth);

     if (amount < 0)
     {
         if (isInvincible)
         {
             return;
         }

         isInvincible = true;
         invincibleTimer = timeInvincible;
     }

     if (currentHealth < 1)
     {
         Debug.Log("Game Over!");
     }

     if (currentHealth > 10)
     {
         currentHealth = 10;
     }
 }
