//Hello everybody, something went wrong with this code but i can't find what. I need some help. thanks

var cashRegister = {
    total:0,
    lastTrasactionAmount:0,
    //Dont forget to add your property
    add: function(itemCost) {
        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;
    },
    //Add the voidLastTransaction Method here
    voidLastTransaction: function(){
        this.total -=  this.lastTransactionAmount;
    }
};

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransaction();
cashRegister.scan('eggs',4);
cashRegister.scan('eggs',1);
cashRegister.scan('eggs',3);


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

Since there is no question we can only believe the error message... Something is wrong. This inevitibly leads to a deviation from the instructions. Sucks to be busted.

Since when is that 3 chocolates?
