help me please!

Oops, try again. It looks like you have an error in your code! Check the error message for more details: ReferenceError: applyStaffDiscount is not defined

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('alex',20);

};

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

applyStaffDiscount('me')

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


#2

applyStaffDiscount is a method of cashRegister object, to call a method of an object do:

objectName.methodName(arguments)

you can also look at how you called the scan method, which is also a method of cashRegister object


#3

thanks, but I'm still here.
change for:
cashRegister.applyStaffDiscount('me')
mistake:"Oops, try again. false"


#4

here:

cashRegister.applyStaffDiscount('me')

me shouldn't be a string, a string has no discountPercent propertyName.

you should pass the me object you created here:

// Create yourself again as 'me' with a staff discount of 20%

var me = new StaffMember('alex',20);

as argument to calling applyStaffDiscount
