# Stuck at "You Deserved it!" - What seems to be the problem?

#1

Stuck on this exercise. Error message says: Oops, try again. false and that's that. Console prints the total but still.

``````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("Angelo", 20);

var cashRegister = {
total:0,
lastTransactionAmount: 0,
this.total += itemCost;
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

Heyyo, this is the section where you have a problem:

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

#3

To add on to what powell is saying, this is what your code translates to:
this.total = this.total * 20% (or .2).

So does the employee discount mean that you only pay 20% of the total? Or do you get 20% off of the total?

Special Note:
I calculated the problem a little differently and got a false answer as well, even though the total was right.
My logic was this: this.total * (100- employee.discountPercent)/100 = discount taken off
However, the "correct" logic is this.total -= this.total * employee.discountPercent/100. Could throw some people off.
