Can't change stats of the current character

Hello,

By advance sorry for my english.

Well I try to do some little RPG with multiple characters(party system etc) and I'm struggling a lot.

Right now what I m trying to do is :when the next button or previous button is clicked stats of the previous/next character is displayed.

I already create a script in scriptableObject+scriptable objects themself where the stats of the players are stored,a small script with an array where are stored all the gameobjects containing the main script in which the scriptableObject is referenced. the script changing the array to ++ seems to work but the stats display itself is not done.

I tried many combinaison,I spent more than 10h on it today ,so I hope someone can help me.

I let you some element of my code here .

script of the button :

 public class NextCharButton : MonoBehaviour {
     public GameObject[] characterGroup;
     private int currentCharacter;
     public void NextScene(){
         characterGroup [currentCharacter].SetActive (false);
         if (currentCharacter >= characterGroup.Length - 1) {
             currentCharacter = 0;
             characterGroup [currentCharacter].SetActive (true);
          
         } else {
             currentCharacter++;
             characterGroup [currentCharacter].SetActive (true);
          
         }
     }
     // Use this for initialization
     void Start () {
         for (int i = 0; i < characterGroup.Length; i++) {
             characterGroup [i].SetActive (false);
             currentCharacter = 0;
             characterGroup [0].SetActive (true);
         }
     }

main script(most important element) // playerstatsscriptable = ref to another script used for create the scriptableObject >>public class PlayerStats : ScriptableObject
