Why won't my power up work to buff my sword?

So i'm trying to make the damage on my sword go from 50 up to 100 once I walk into a power up orb. This process should also activate the fire particle system which is a child of my sword already. I've had to rewrite this a number of times due to different errors and in my simplifying it I think I've lost sight of any alternate way of doing it...but I usually get any number of errors from this when I actually collide with the power up. Any help is appreciated.

script 1: On Sword

static var fireActive = false;

function Update (){ if (fireActive){ Damage += 50; fireActive = false; }

script 2: On Fire

var preFireBuffed : int = MeleeSystem.Damage; var fireBuffed : int = MeleeSystem.Damage + 50; static var Fire : Transform; //filled with particle system Fire

function Update(){ if (Fire.active){ MeleeSystem.fireActive = true; } }

script 3: On Power Up Orb

var Power : Transform; // the particle system called Fire var energySource : Transform; //the collider that this code is on var weapon : Transform; //filled with my sword which is active

function OnTriggerEnter (theCollider : Collider){ if (theCollider.tag == "Player" && weapon.active == true){ FireBuff.Fire1 = true; Power.active = true; Destroy(gameObject); } }
