So I have been struggeling with this project for quite a while now. Can someone please tell me where my problem is with the Status: Closed part, I cant seem to find the solution. I have redo the project 3 times now and trying to find something different even trying to use an AI tool to see if that helps with the problems but it just caused even more. Can someone maybe help me with this?

amountFromUnit += unitValue;
}
if (amountFromUnit > 0) {
changedArray.push([unit, amountFromUnit / 100]); // Convert back to dollars
}
}
}
// If we couldn't give exact change
if (remainingChange > 0) {
return {
status: 'INSUFFICIENT_FUNDS',
change: []
};
}
// If the total cash in the drawer equals the change due, return CLOSED
if (totalCidInCents === changeDueInCents) {
return {
status: 'CLOSED',
change: cid
};
}
// Otherwise, return the calculated change
return {
status: 'OPEN',
change: changedArray
};
};
// Format the change into a string for display
const formatChange = changedArray => {
return changedArray.map(([unit, amount]) => `${unit}: $${amount.toFixed(2)}`).join('<br>');
};
should i try and test it like that and try to figure out the problem from there?
