Item Collection with Raycast / C#

Dear Community,

After watching several tutorials and study the Unity Libraries, my c# script still won't work correctly. My C# Knowledge isn't that big yet, so this script might be pretty easy to understand for people with C# experience here :)

The goal is it, to create a script that allows the player to collect an item only by looking at it (in the range of 5.0f) and pressing a key (for example "e").

Did i miss something?

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class ItemRaycast : MonoBehaviour
 {
     public GameObject Item;
     public GameObject PickupText;
     public RaycastHit Hit;
 
     private void Start()
     {
         PickupText = this.gameObject.transform.GetChild(0).GetChild(0).gameObject;
     }
 
     // Update is called once per frame
     void Update()
     {
         var fwd = transform.TransformDirection(Vector3.forward);
 
         if (Physics.Raycast(transform.position, transform.forward, out Hit, 5.0f) && Hit.collider.gameObject.tag == "Item")
         {
             //Show item name
             PickupText.SetActive(true);
 
             if (Input.GetKeyDown("e"))
             {
                 //Do Something
                 Destroy(this.gameObject);
             }
         }
     }
 }
