EditorGUILayout.EnumPopup not found

I have this simple editor script and I can't seem to find the problem.

 using UnityEngine;
 using System.Collections;
 
 public class Info : MonoBehaviour {
 
     public enum Category {Armor, Consumable, Necklace, Ring, Scroll, Shield, Weapon}
     public enum ArmorType {Breast, Feet, Hands, Head, Shoulder}
 
     public string Name;
     public Category category;
     public ArmorType armorType;
     public int Armor;
     public int Health;
     public int Mana;
     public int Attack;
     public int Intelligence;
 }

Editor script is here; The 2 with the enumpopup do not work, it says missing category and armortype.

 using UnityEngine;
 using UnityEditor;
 using System.Collections.Generic;
 using System.Collections;
 using System;
 
 [CustomEditor(typeof(Info))]
 public class InfoEditor : Editor
 
 {
     bool myBool = false;
 
     public override void OnInspectorGUI()
     {
         myBool = EditorGUILayout.Toggle ("Show Original", myBool);
         if (myBool == true) base.OnInspectorGUI();
         Info myTarget = (Info)target;
 
         myTarget.Name = EditorGUILayout.TextField("Name", myTarget.Name);
         myTarget.category   = (Category )EditorGUILayout.EnumPopup("Category",  myTarget.category); // Error message here
         myTarget.armorType     = (ArmorType)EditorGUILayout.EnumPopup("Armor Type",myTarget.armorType); // Error message here
 
         if (myTarget.category.ToString() == "Consumable"){
             myTarget.Health = EditorGUILayout.IntField("Health", myTarget.Health);
             myTarget.Mana = EditorGUILayout.IntField("Mana", myTarget.Mana);
         }
         if (myTarget.category.ToString() == "Armor"){
             myTarget.Armor = EditorGUILayout.IntField("Armor", myTarget.Armor);
             
         }
     }
 }

When I comment out those 2 errors everything else works. Could anyone find where the problem is?
