Parent mesh problem

I made a video to show what excacly happens. You can see me dragging the 2 weapons into the hierarchy, they appear in the scene. Then when I click on the play button, I show you where the 2 weapons are located at the beginning of the game and I show you what happens if I scroll down. When I scroll down the Axe scales way down but stays at the same position.

Here follows the code:

 #pragma strict
 
 public var weapons : GameObject[];
 
 private var currentw : int;
 private var nmrweapons : int;
 private var weaponslot : Transform;
 
 
 
 function Start () {
 
 weaponslot = transform.Find("male_model@Idle/male_model/malemodel|forearm.R.001/malemodel|hand.R/Empty_weapon");
 weapons = GameObject.FindGameObjectsWithTag("Weapon");
 currentw = 0;
 nmrweapons = weapons.Length;
 Debug.Log("test");
 }
 
 function Update () {
 
 if(Input.GetAxis("Mouse ScrollWheel")<0) {
 
     if(currentw == nmrweapons){
     currentw = 0;
     }
     else{
     currentw = 1;
     }
     Debug.Log("test1");
     Changeweapon(currentw);
     
     }
 }
 
 function Changeweapon(cw:int){
 
 Debug.Log("test3");
 weapons[cw].transform.parent = weaponslot;
 weapons[cw].transform.localPosition = Vector3.zero;
 weapons[cw].transform.localRotation = Quaternion.identity;
 weapons[cw].transform.localScale = Vector3.one;
 
 }

I really do not understand anymore what to do, I've tried loads of things. But I just do not have enough knowledge of coding, so I really do need someone to explain me, why its doing what its doing. I am still new at coding so it's probably a dumb mistake.

Thanks in advance
