Why is my cash register code not passing

JavaScript

I wrote the code and tried it multiple times nothing seems to work if anyone have any suggestion
here is my code:;

//code
const buyButton=document.getElementById("purchase-btn")
const change=document.getElementById("change-due")

//values
let price = 19.5;
let cid =[["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]];
 
//for cid worth
const equiv=[0.01,0.05,0.1,0.25,1,5,10,20,100]
for(let c=0;c<cid.length;c++){
  cid[c][2]=Math.ceil(cid[c][1]/equiv[c])
  cid[c][1]=equiv[c]
  }
const cidR=cid.reverse()
console.log(cidR)

//check
let sum=0
const check=()=>{
      cidR.forEach(num=>
      {if(num[2]!==0){sum++}
      console.log(sum)}
    )}

// to get the index and times
const formula=()=>{
  const cash=document.getElementById("cash").value

  //change
  if(cash-price>0){
    let status
    let text
    let remain=cash-price
    for(let c=0; c<7&&remain!==0; c++){
      const finder=cidR.findIndex(value=>
      value[1]<=remain&&value[2]>0)
      if(finder>=0){
      let times=Math.floor(remain/cidR[finder][1])
      if(times>cid[finder][2])(times--)
      cidR[finder][2]-=Math.floor(remain/cidR[finder][1])
      remain-=cidR[finder][1]*times
      remain=remain.toFixed(2)
      text+=cid[finder][0]+': '+'$'+cidR[finder][1]    *times+' '
    console.log(cidR[finder])}
    else if(finder<0&&remain>0){change.textContent="Status: INSUFFICIENT_FUNDS"}} 
    check()
if(sum==0&&remain==0){
  status="CLOSED"
  change.textContent=status+' '+text.replace('undefined','')
}else if(sum!==0&&remain==0){
  status="OPEN"
  change.textContent=
  `Status: ${status} ${text.replace('undefined','')}`
  }

                  }
  
  //equal
  else if(cash==price){change.textContent="No change due - customer paid with exact cash"}

  
  //no money
  else if(cash<price){alert("Customer does not have enough money to purchase the item")}
}

//button
buyButton.addEventListener('click',formula)

All of this code floating around inside of the global space needs to be inside of your functions.

hi there,
I’m concerned by this statement that you made.

You should be writing a small amount of code to do something specific and check it works before writing more.
For example, maybe make sure your purchase button will trigger an event. Then after that, work on one of the testcases, which ever one is easiest for you.

hi sorry I don’t know what got to me, I worded it incorrectly I forgot to say the code works perfectly it’s just that the project isn’t getting a completion
