7/7 Building a cash register- You deserved it!

<In what way does your code behave incorrectly? Include ALL error messages.>

The code seems to work over all, but the browser is printing “Your bill is NaN.”
I also get an error message saying “Oops, try again: false”

```

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(“jocelyn”, 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.total * ( 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));

@designjumper55560,
In your function call

cashRegister.applyStaffDiscount("me");

you are using a string Value “me” as an argument
whereas you required argument should be an object
which you assigned to the variable me

Try it by using

cashRegister.applyStaffDiscount(me);
