How do I access the instance variables of a scriptable object?

Hello,
I am trying to implement an RPG style inventory, and I found a patter I really like, using ScriptableObjects.
The problem comes when I am trying to add a Instance class, so that I can make two different instances of the object have different values.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

[System.Serializable]
[CreateAssetMenu(menuName = "Item")]
public class Item : ScriptableObject
{
    public enum Type { misc, head, neck, ring, weapon, armor, light_source }
    public enum Slot { general, head, neck, finger, hand, torso, leg, foot }
    public string itm_Name, itm_Desc, itm_FullName, itm_Lore;
    public bool itm_Magical;
    public Type itm_Type;
    public Slot itm_Slot;
    public float itm_Value;
    public int itm_Quality, itm_AttackBonus, itm_MinDamage, itm_MaxDamage, itm_DefenseBonus, itm_MaxCharges, itm_MaxFuel, itm_CurrentFuel, itm_Icon;
    public int itm_ID_Quality, itm_ID_AttackBonus, itm_ID_Damage, itm_ID_Defense, itm_ID_Charges; //these are the modifiers for how the item changes if it is IDd

    [System.Serializable]
    public class ItemInstance
    {
        public Item item;
        public bool itm_ID, itm_Active;
        public int itm_CurrentCharges, itm_CurrentFuel;

        public ItemInstance(Item _item, bool _ID, bool _Active, int _CurrentCharges, int _CurrentFuel)
        {
            this.item = _item;
            this.itm_ID = _ID;
            this.itm_Active = _Active;
            this.itm_CurrentCharges = _CurrentCharges;
            this.itm_CurrentFuel = _CurrentFuel;
        }
    }

    public void GetDamage()
    {
        int _result = 0;
        _result = Random.Range(this.itm_MinDamage, this.itm_MaxDamage);
        if (instance.itm_ID) _result += this.itm_ID_Damage;
    }
}

The problem comes that when I try to implement that GetDamage() method: if (instance.itm_ID)
I cannot access the itm_ID variable to check if an item is identified. Any suggestions?

Ok, I think I found the answer!

[System.Serializable]
[CreateAssetMenu(menuName = "Item")]
public class Item : ScriptableObject
{
    public enum Type { misc, head, neck, ring, weapon, armor, light_source }
    public enum Slot { general, head, neck, finger, hand, torso, leg, foot }
    public string itm_Name, itm_Desc, itm_FullName, itm_Lore;
    public bool itm_Magical;
    public Type itm_Type;
    public Slot itm_Slot;
    public float itm_Value;
    public int itm_Quality, itm_AttackBonus, itm_MinDamage, itm_MaxDamage, itm_DefenseBonus, itm_MaxCharges, itm_MaxFuel, itm_CurrentFuel, itm_Icon;
    public int itm_ID_Quality, itm_ID_AttackBonus, itm_ID_Damage, itm_ID_Defense, itm_ID_Charges; //these are the modifiers for how the item changes if it is IDd

    [System.Serializable]
    public class ItemInstance
    {
        private Item item;
        private string itm_Name, itm_FullName;
        public bool itm_ID, itm_Active;

        public ItemInstance(Item _item)
        {
            this.item = _item;
            this.itm_Name = _item.itm_Name;
            this.itm_FullName = _item.itm_FullName;
            this.itm_ID = false;
        }

        public string GetName()
        {
            string _result = "";
            if (!this.itm_ID) _result = itm_Name;
            if (this.itm_ID) _result = itm_FullName;
            return _result;
        }

        public void ID_Item() { this.itm_ID = true; }
    }
}

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class GameManager : MonoBehaviour
{
    public Item ref_item;

    // Start is called before the first frame update
    void Start()
    {
        Item.ItemInstance item1 = new Item.ItemInstance(ref_item);
        Item.ItemInstance item2 = new Item.ItemInstance(ref_item);

        item2.ID_Item();
        Debug.Log("This is the First Sword: " + item1.GetName());
        Debug.Log("This is the Second Sword: " + item2.GetName());
    }

    // Update is called once per frame
    void Update()
    {
        
    }
}

just a brief test here, but IF I REMEMBER TO ASSIGN ref_Item IN THE INSPECTOR(!!!) then it works.
(sorry for the all caps, but you would not believe how much time I lost screaming at my computer because I forgot to do that.)
