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.
