NullReferenceException: Object reference not set to an instance of an object

This is Almost the same error as before but This Stops the game totaly.

It points at lines: 44 and 18.

It doesn't display the skills correctly like Melee_ Offence and mele_defence and so on. I'm watching this tutorial:

using UnityEngine; using System.Collections; using System;

 public class CharacterGenerator : MonoBehaviour {
     private PlayerCharacter _toon;
     // Use this for initialization
     void Start () {
         _toon = new PlayerCharacter();
         _toon.Awake();
     }
     
     // Update is called once per frame
     void Update () {
     
     }
     
     void OnGUI()
     {
         DisplayName();
         DisplayAttributes();
         DisplayVitals();
         DisplaySkills();
         
     }
     
     private void DisplayName()
     {
         GUI.Label(new Rect(10, 10, 50,  25), "Name:" );    
         _toon.Name = GUI.TextArea(new Rect(65, 10, 120, 25), _toon.Name);
             
     }
     
     private void DisplayAttributes()
     {
         for(int cnt = 0; cnt < Enum.GetValues(typeof(AttributeName)).Length; cnt++)
         {
             GUI.Label(new Rect(10, 40 + (cnt * 25), 100, 25), ((AttributeName)cnt).ToString() );
             GUI.Label(new Rect(115, 40 + (cnt * 25), 30, 25), _toon.GetPrimaryAttribute(cnt).AdjustedBaseValue.ToString() );
         }
     }
     
     private void DisplayVitals()
     {
             for(int cnt = 0; cnt < Enum.GetValues(typeof(VitalName)).Length; cnt++)
         {
             GUI.Label(new Rect(10, 40 + ((cnt + 7) * 25), 100, 25), ((VitalName)cnt).ToString() );
             GUI.Label(new Rect(115, 40 + ((cnt + 7) * 25), 30, 25), _toon.GetVital(cnt).AdjustedBaseValue.ToString() );
         }
     }
     
     private void DisplaySkills()
     {
                 for(int cnt = 0; cnt < Enum.GetValues(typeof(SkillName)).Length; cnt++)
         {
             GUI.Label(new Rect(150, 40 + (cnt * 25), 100, 25), ((SkillName)cnt).ToString() );
             GUI.Label(new Rect(255, 40 + (cnt * 25), 30, 25), _toon.GetSkill(cnt).AdjustedBaseValue.ToString() );
         }
     }
 }

And this is the class where I get my SkillName and VitalName.

 using UnityEngine;

     {
         _name = string.Empty;
         _level = 0;
         _freeExp = 0;
         
         _primaryAttribute = new Attribute[Enum.GetNames(typeof(AttributeName)).Length];
         _vital = new Vital[Enum.GetValues(typeof(VitalName)).Length];
         _skill = new Skill[Enum.GetValues(typeof(SkillName)).Length];
         
         SetupPrimaryAttribute();
         SetupVitals();

     }

     }

         set{ _level = value;}
     }

     {

         set{ _freeExp = value; }
     }
     
     public void AddExp(uint exp)
     {
         _freeExp += exp;

     }
