4/7 what am i missing?


#1
var cashRegister = {
    total:0,
    add: function(itemCost){
        this.total += itemCost;
    },
    scan: function(item,quantity) {
        switch (item) {
        case "eggs": this.add(0.98); break;
        case "milk": this.add(1.23); break;
        case "magazine": this.add(4.99); break;
        case "chocolate": this.add(0.45); break;
        }
    }
};

// scan each item 4 times
cashRegister.scan("eggs",4);
cashRegister.scan("milk",4);
cashRegister.scan("magazine",4);
cashRegister.scan("chocolate",4);
//Show the total bill
console.log('Your bill is '+ cashRegister.total);

#2

Missing multiplier...

case "eggs": this.add(0.98 * quantity); break;

Same applies in the other cases.
