Tell us what’s happening:

i passed all the tests, except the last one, although i have the exact right outcome…
i’m really confused as i put a lot of time in this and finally got a working code, but it won’t let me pass…

Is there maybe a bug or some hidden feature the test is looking for?

i’ll post the code below. I know it’s ugly but it works…just the last test…

Your code so far

let price = 19.5;
let cid = [
  ["PENNY", 0.5],
  ["NICKEL", 0],
  ["DIME", 0],
  ["QUARTER", 0],
  ["ONE", 0],
  ["FIVE", 0],
  ["TEN", 0],
  ["TWENTY", 0],
  ["ONE HUNDRED", 0]
];

const cash = document.getElementById("cash");
const changeDue = document.getElementById("change-due");
const purchaseBtn = document.getElementById("purchase-btn");
let cashInDrawer = 0;

  if (cash.value < price) {
  alert("Customer does not have enough money to purchase the item")}
  else if (cash.value.toString() === price.toString()) {
    changeDue.textContent = "No change due - customer paid with exact cash";
    
  }

I think we need your HTML too.

found a solution myself by changing the scope of a variable after reading about it in this thread
