Need help with setting all items of a specific tag to "inactive" when i die.

I am making a platform level and my death trigger looks like this. the level is based around hitting switches to activate the next platform. but when i die, i want the platforms to go back to how they were when the level started, inactive.

 var spawn : Transform;
 var platforms : GameObject[];
 
 platforms = GameObject.FindGameObjectsWithTag("platforms");
 
 function OnTriggerEnter(other : Collider)
 {
     if (other.tag == "Player")
     {
        
         other.transform.position = spawn.position;
         audio.Play();
         platforms.SetActive(false);
     }
     
 }

I want the game objects with the tag "platforms" to be set to inactive when i cross the death trigger, effectively starting the level over.

but right now, nothing is happening, im respawning, but the platforms are still active.
