Replace this line with your code. 
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 ("Kate",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){
        return this.total-(this.total*0.1*this.discountPersent);
    }
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',3);
// Apply your staff discount by passing 
console.log('Your bill is '+cashRegister.total.toFixed(2));
/*thats what they prompt :did you scan all the items */

@arraysolver36165,

// Apply your staff discount

I see where you went wrong. Here:
applyStaffDiscount: function (employee){
return this.total-(this.total*0.1*this.discountPersent);
}
};

They want you to change employee. So here is a example of my code:

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

};
