CharacterBase script has 41 errors repeating

The title pretty much says it. I get 41 errors on the CharacterBase script by using the tutorial from BurgZergArcade. The person typing didn't get a single error but I got 41 and they all repeat each other. As far as I can tell, my script is pretty much exactly the same but there might be something in there I can't see.

 using UnityEngine;
 using System.Collections;
 using System;               //added to access the enum class
 
 public class BaseCharacter : MonoBehaviour {
     private string _name;
     private int _level;
     private uint _freeExp;
     
     private Attribute[] _primaryAttribute;
     private Vital[] _vital;
     private Skill[] _skill;
     
     public void Awake() {
         _name = string.Empty;
         _level = 0;
         _freeExp = 0;
         
         _primaryAttribute = new Attribute[Enum.GetValues(typeof(AttributeName)).Length];
         _vital = new Vital[Enum.GetValues(typeof(VitalName)).Length];
         _skill = new Skill[Enum.GetValues(typeof(VitalName)).Length];
         
         SetupPrimaryAttributes();
         SetupVitals();
         SetupSkills();
         
     }
     
     public string Name {
         get{ return _name; }
         set{ _name = value; }
     }
     
     public int level {
         get{ return _level; }
         set{ _level = value; }
     }
     
     public uint FreeExp {
         get{ return _freeExp; }
         set{ _freeExp = value; }
     }
     
     public void AddExp(uint exp) {
         _freeExp += exp;
         
         CalculateLevel();
     }
     
     
     // take avg of all players skills and assign that as the player level
     public void CalculateLevel() {
     }

     }

         }
     }
     
     private void SetupSkills() {
         for(int cnt = 0; cnt < _skill.Length; cnt ++) {
             _skill[cnt] = new Skill();
         }
     }
     
     public Attribute GetPrimaryAttribute(int index) {
         return _primaryAttribute[index];

         energyModifier.ratio = 1;
         
         GetVital((int) VitalName.Health).AddModifier(energyModifier);
         
         //mana
        ModifyingAttribute manaModifier = new ModifyingAttribute();
         manaModifier.attribute = GetPrimaryAttribute((int)AttributeName.Willpower);
         manaModifier.ratio = 1;
         
         GetVital((int) VitalName.Health).AddModifier(energyModifier);
 }

         //magic defence
         GetSkill((int)SkillName.Magic_Offence).AddModifier(new ModifyingAttribute(GetPrimaryAttribute((int)AttributeName.Concentration), .33f));

         //ranged offence
         GetSkill((int)SkillName.Ranged_Offence).AddModifier(new ModifyingAttribute(GetPrimaryAttribute((int)AttributeName.Concentration), .33f));
         GetSkill((int)SkillName.Ranged_Offence).AddModifier(new ModifyingAttribute(GetPrimaryAttribute((int)AttributeName.Speed), .33f));
         //ranged defence
         GetSkill((int)SkillName.Ranged_Offence).AddModifier(new ModifyingAttribute(GetPrimaryAttribute((int)AttributeName.Speed), .33f));
         GetSkill((int)SkillName.Ranged_Offence).AddModifier(new ModifyingAttribute(GetPrimaryAttribute((int)AttributeName.Nimbleness), .33f));
     }
     
     public void StatUpdate() {
         for(int cnt = 0; cnt < _vital.Length; cnt++)
             _vital[cnt].Update();
         
         for(int cnt = 0; cnt < _skill.Length; cnt++)
             _skill[cnt].Update();
     }
 }

Hopefully someone will be able to find the errors I can't see. And no, I don't want another script, I want to fix the one I have.
