Tell us what’s happening:

I am confused on what it means by “fourth object” i know its in the “const locations” array.

Your code so far

let xp = 0;
let health = 100;
let gold = 50;
let currentWeapon = 0;
let fighting;
let monsterHealth;
let inventory = ["stick"];

const button1 = document.querySelector('#button1');
const button2 = document.querySelector("#button2");
const button3 = document.querySelector("#button3");
const text = document.querySelector("#text");
const xpText = document.querySelector("#xpText");
const healthText = document.querySelector("#healthText");
const goldText = document.querySelector("#goldText");
const monsterStats = document.querySelector("#monsterStats");
const monsterName = document.querySelector("#monsterName");
const monsterHealthText = document.querySelector("#monsterHealth");
const weapons = [
  { name: 'stick', power: 5 },
  { name: 'dagger', power: 30 },
  { name: 'claw hammer', power: 50 },
  { name: 'sword', power: 100 }
];
const monsters = [
  {
    name: "slime",
    level: 2,
    health: 15
  },
  {
    name: "fanged beast",
    level: 8,
    health: 60
  },
  {
    name: "dragon",
    level: 20,
    health: 300
  }
]
const locations = [
  {
    name: "town square",
    "button text": ["Go to store", "Go to cave", "Fight dragon"],
    "button functions": [goStore, goCave, fightDragon],
    text: "You are in the town square. You see a sign that says \"Store\"."

    } else {
      text.innerText = "You do not have enough gold to buy a weapon.";
    }
  } else {
    text.innerText = "You already have the most powerful weapon!";
    button2.innerText = "Sell weapon for 15 gold";
    button2.onclick = sellWeapon;
  }
}

function sellWeapon() {

    gold += 15;
    goldText.innerText = gold;

Look at your locations array, there are four objects in there, the fourth is also the last one. You need to use the right index to access it and pass it to the function
