var cashRegister = {
total: 0,
//insert the add method here
add: function(itemCost)
{
this.total += itemCost;
},

scan: function (item) {
    switch (item) { 
    case "eggs": 
        this.add(0.98); 
        break;

    case "milk": 
        this.add(1.23); 
        break;

    //Add other 2 items here
    case "magazine":
        this.add(4.99);
        break;
    case "chocolate":
        this.add(0.45);
        break;
    }
    return true;
}

};

//Scan 2 eggs and 3 magazines
cashRegister.scan("eggs");
cashRegister.scan("eggs");
cashRegister.scan("magazines");
cashRegister.scan("magazines");
cashRegister.scan("magazines");

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

Oops, try again.
Have you scanned eggs twice and magazine three times?
