Error with my script

I have fixed the obvious errors baring the fact that I do no have access to these classes

 PF1_IO
 LAA
 LAA_Items
 LAA_Weapons
 LAA_Defense
 and do not know if there are any other further errors.

The main problem though was ther is a lot of missing data. I placed temporary place holders so that you can find and fix the problems. Here is the modified code

 using UnityEngine;
 using System.Collections;
 
 public class MainInv_Lab3 : MonoBehaviour
 {
     PF1_IO myIO;
     LAA_Inventory  inv;
     LAA_Items  tempItems;
     LAA_Weapons  tempWeapons;
     LAA_Defense tempDefense;
 
     enum STATE { none, name, value, att_def, inputItem };
 
     STATE curState = STATE.none;
 
     string iName = "";
     int value = 0;
     int att_def = 0;
 
     string userInput;
     
     // fill in this information below with the correct data
     string missingUserInput1 = "1";      // you need to set the appropriate value for this below, you can then remove this
     string missingUserInput2 = "2";      // you need to set the appropriate value for this below, you can then remove this
 
     string tempString1 = "1";            // you need to set the appropriate value for this below, you can then remove this
     string tempString2 = "2";            // you need to set the appropriate value for this below, you can then remove this
 
     int inventoryItems = 5;              // you need to set the appropriate value for this below, you can then remove this
     
     string yourInventory = "X, Y, Z";    // you need to set the appropriate value for this below, you can then remove this
     string yourInventory1 = "X";         // you need to set the appropriate value for this below, you can then remove this
     string yourInventory2 = "Y";         // you need to set the appropriate value for this below, you can then remove this

                 {
