JavaScript Algorithms and Data Structures Projects - Cash Register

My code doesnt work. What am I doing wrong?

``````function checkCashRegister(price, cash, cid) {
const currencyValues = {
"PENNY": 0.01,
"NICKEL": 0.05,
"DIME": 0.1,
"QUARTER": 0.25,
"ONE": 1,
"FIVE": 5,
"TEN": 10,
"TWENTY": 20,
"ONE HUNDRED": 100
};

let changeDue = cash - price;
let change = [];

// Calculate total cash in drawer
let totalInDrawer = cid.reduce((total, curr) => total + curr[1], 0);

// Check if drawer has enough cash
if (totalInDrawer < changeDue) {
return {status: "INSUFFICIENT_FUNDS", change: []};
}

// Check if drawer has exact change
if (totalInDrawer === changeDue) {
return {status: "CLOSED", change: cid};
}

// Iterate over currency denominations in reverse order
for (let i = cid.length - 1; i >= 0; i--) {
let denomination = cid[i][0];
let denominationValue = currencyValues[denomination];
let denominationCount = Math.floor(cid[i][1] / denominationValue);
let amountToReturn = 0;

// Calculate how much of this denomination to return
while (changeDue >= denominationValue && denominationCount > 0) {
changeDue = parseFloat((changeDue - denominationValue).toFixed(2));
amountToReturn += denominationValue;
denominationCount--;
}

// Add denomination to change array if it was used
if (amountToReturn > 0) {
change.push([denomination, amountToReturn]);
}
}

// Check if change could not be made with exact denominations
if (changeDue > 0) {
return {status: "INSUFFICIENT_FUNDS", change: []};
}

// Return the change array
return {status: "OPEN", change: change};
}

checkCashRegister(19.5, 20, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]);
