Pickup script error

Okay so the pick up script works great i can pick up my object and have it apear in my characters hand.

 using UnityEngine;
 
 using System.Collections;
 
 public class PlaceItem : MonoBehaviour 
 
 {
 
     private bool inRange = false;
 
     public bool Activated { get; set; }
 
     void Awake()
     {
     
 
     }
 
    void OnTriggerEnter()
     {
         inRange = true;
         Debug.Log("in range of alter place item");
     }
 
    void OnTriggerExit()
    {
 
         inRange = false;
 
         Debug.Log("out of range of alter ");
     }
 
     void Update()
     {
 
          if (TP_Controller.Instance.ObjectHeld != null)
          {
 
                 if (inRange && TP_Controller.Instance.IsHolding == Input.GetKeyDown(KeyCode.E))
 
             {
                 animation.Play("WIN");// if the item has an animation 
                 //transform.Find("SuperOrb1").renderer.enabled = true;
 
                 TP_Controller.Instance.IsHolding = false;
                 Activated = true;
                 GameObject.Destroy(TP_Controller.Instance.ObjectHeld.gameObject);
                 TP_Controller.Instance.Use(); //-- this will animate the character in CControler and animator 
                }
          }
     }
 }

This script allows me to place the item on a trigger when the character is holding the item then press E to add to the alter.

The problem is that when i go to the alter and press E without the object held it still activates, can anyone help ?
