GameObject[] doesn't have a definition for transform/name/etc...

I have a pick up script that has GameObject[] for the code FindGameObjectsWithTag.

This is my script:

 using UnityEngine;
 using System.Collections;
 using CameraRayCastLine;
 using PickUpSphereCast;
 
 namespace CarryingItems {
 
     public class PickUp : MonoBehaviour {
         
         
         // The variables for the positions.
             // Forward drop offset.
                 public float OffsetDropPosition = 2;
                 
         // The boolean that checks if the camera's RayCast is hit.
             public bool CameraRayHit;
         
         // The Player and the tagged objects.
             public GameObject Camera;
             public GameObject[] CarryableObject;
             public GameObject Character;
             public Transform CharacterTransform;
             
         // Is an item picked up at the moment?
             public bool ItemPickedUp;
         
         // Are you in the item's SphereCast?
             public bool InItemSpherecast;
             
         // Are you looking at an item?
             public bool LookingAtObject;
         
         
         void Awake() {
             // The origin of the objects.
                 Camera = GameObject.Find("MainCamera");
                 CarryableObject = GameObject.FindGameObjectsWithTag("CarryableObjects");
                 Character = GameObject.Find("Character");
                 CharacterTransform = GameObject.Find("Character").transform;
             // The code that references the RayCast script of the camera.
                 CameraRayHit = Camera.GetComponent<CameraRayCastLine.PickUpRayCast>().CameraRayCast;
             // The code that references the SphereCast of another script.
                 InItemSpherecast = PickUpSphereCast.ItemPickUpSphereCast.ItemSphereCast;
         }
 
         void Start() {
             // The code that tells you how to pick up an object through the debug log.
                 Debug.Log("Press E to pick up an object.");
         }
         
         void Update() {
             
         }
         
         void PickUpItemCode() {
             // If another item isn't picked up at the moment.
                 if(ItemPickedUp == false) {
                     Debug.Log("No items picked up.");
                     // If you're in the SphereCast.
                         if(InItemSpherecast == true) {
                             Debug.Log("Spherecast = true.");
                             // If you're looking at the item.
                                 if (CameraRayHit == true) {
                                     // A boolean for the GUI.
                                         LookingAtObject = true;

                                         Debug.Log("Press E to pick up the" + CarryableObject.name + ".");
