Error CS1061, help

This is the error: Assets/Scripts/Character Classes/BaseCharacter.cs(66,48): error CS1061: Type Attribute' does not contain a definition for Name' and no extension method Name' of type Attribute' could be found (are you missing a using directive or an assembly reference?)

This is the line it says the error is in: _primaryAttribute[cnt].Name = ((AttributeName)cnt).ToString();

I dunno what's wrong :[

Code:

 public class BaseCharacter : MonoBehaviour {
 
     private string _name;
     private int _level;
     private uint _freeExp;
 
     private Attribute[] _primaryAttribute;

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