My gameobject disappears when I transform it

I am new to unity and programming in general, so excuse me if this is a simple question. I am trying to get a gameobject become twice as large and move to the player's position once when the player interacts with it. However, whenever it moves the gameobject, it disappears from the game but I can still see it in the scene view. Any help would be appreciated. Below is my code and a screenshot of what I described.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 public class PickupScript : MonoBehaviour {
     Transform camerapos;
     Transform size;
     int scaled = 0;
     public GameObject cam;
     void Start()
     {
         size = GetComponent<Transform> ();
         camerapos = cam.GetComponent<Transform> ();
     }
     void OnTriggerEnter2D(Collider2D col) {
         if (globalvar.interact) {
             if (scaled == 0) {
                 size.localScale = new Vector2 (2, 2);
                 size.position = camerapos.position;
                 scaled = 1;
             }
         }
     }
     void OnTriggerStay2D(Collider2D col) {
         if (globalvar.interact) {
             if (scaled == 0) {
                 size.localScale = new Vector2 (2, 2);
                 size.position = camerapos.position;
                 scaled = 1;
             }
         }
     }
 }
