"You deserved it" correct but wrong


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("peter",20);

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


// Apply your staff discount by passing the 'me' object
// to applyStaffDiscount

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

above are my codes, it does not have any syntax errors and the result is correct(13.74), but it keeps telling me "try again, false" please help me find why


missing ) in function?


this.total =this.total * (100-employee.discountPercent)/ 100;
That shouldn't be equals. You want to subtract 20% of the total from the total. It should be:
this.total - (this.total * (100-employee.discountPercent)/ 100));

Hope that helps!


I don't understand why the me in cashRegister.applyStaffDiscount(me); isn't in quotes like the properties in cashRegister.scan methods. Can anyone clarify that for me? Thank you.


me here is a variable actually a new object. Only 'string' literals need to be passed in 'quotes'
