How do I make the objects on my list activate according to the variable?

Question

I would like to ask a question, I am making a game of ships, I was creating a list with the objects (slots) that would be disabled initially, however they would be activated according to the number of slots stored in the variable, I put it in the script as public and added it in the inspector the objects on the scene in their proper places in the list, but this error appears: "Index was outside the bounds of the array". What would I need to do for this to work?

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class ItensId : MonoBehaviour {

 public GameObject[] Slot;
 public List<Text> IdText;
 private bool InventoryFull;
    
 void Start()
 {
     InventoryFull = false;
     DataBase.CountItens = PlayerPrefs.GetInt("CountItens");
 }

 // Update is called once per frame
 void Update()
 {
     if(ItensContent.buy == true && InventoryFull == false)
     {
         Slot[DataBase.CountItens].SetActive(true);
         ItensContent.buy = false;
     }        
 }

} obs: The calculation of the items is done in a variable from another script.

@Animaki An array starts from 0 ang goes to n-1 with n being the number of thing in your array. You should add - 1 to your 16th line after database.countitems. If you have 3 items the 3rd item will be slot[2] Because: Slot[0] Slot[1] Slot[2]->the third object

Unfortunately not, this is the script that calculates CountItens, it works from a button to select the item (S$$anonymous$$S) and the other to buy the item (Buy). This and the other script are in different scenes. If this information helps you to identify the problem, I am grateful.

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI;

public class ItensContent : $$anonymous$$onoBehaviour { static public string id; private string ChosenItem; static public bool buy;

 void Start()
 {
     buy = false;
 }

 public void Purchase()
 {
     DataBase.CountItens = DataBase.CountItens + 1;
     PlayerPrefs.SetInt("CountItens", DataBase.CountItens);
     id = ChosenItem;
     buy = true;
 }
 public void Sms()
 {
     ChosenItem = "sms";
 }
 public void Home()
 {
     UnityEngine.Scene$$anonymous$$anagement.Scene$$anonymous$$anager.LoadScene("Home");
 }

}

obs: The CountItens variable is in a static script serving only as a stored database.
