<Below this line, in what way does your code behave incorrectly? Include ALL error messages.>
it says Your bill is NaN ; why?

function StaffMember(name,discountPercent){
    this.name = name;
    this.discountPercent = discountPercent;
}

var sally = new StaffMember("Sally",5);
var bob = new StaffMember("Bob",10);

// Create yourself again as 'me' with a staff discount of 20%
var me = new StaffMember("Me",20);

var cashRegister = {
    total:0,
    lastTransactionAmount: 0,
    add: function(itemCost){
        this.total += (itemCost || 0);
        this.lastTransactionAmount = itemCost;
    },
    scan: function(item,quantity){
        switch (item){
        case "eggs": this.add(0.98 * quantity); break;
        case "milk": this.add(1.23 * quantity); break;
        case "magazine": this.add(4.99 * quantity); break;
        case "chocolate": this.add(0.45 * quantity); break;
        }
        return true;
    },
    voidLastTransaction : function(){
        this.total -= this.lastTransactionAmount;
        this.lastTransactionAmount = 0;
    },
    // Create a new method applyStaffDiscount here
    applyStaffDiscount: function(employee){
        this.total -= this.toal * (employee.discountPercent / 100);
    },
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',3);
// Apply your staff discount by passing the 'me' object 
// to applyStaffDiscount
cashRegister.applyStaffDiscount(me);

// Show the total bill
console.log('Your bill is '+cashRegister.total.toFixed(2));

Hi @cloudmaster61463, here:

applyStaffDiscount: function(employee){
        this.total -= this.toal * (employee.discountPercent / 100);

Should be this.total, you missed a ‘t’.

this.total -= this.total * (employee.discountPercent / 100);

You’re welcome. No worries @cloudmaster61463, it’s not a stupid mistake at all. When writing a long code, things tend to slip away.

It happens, me included sometimes. :wink:

Thank you for posting your question & description in such nice format, it helps so much to debug.

Happy coding! Cheers :slight_smile:
