It says oops try again false.


var cashRegister = {
    total:0,
    //Dont forget to add your property
    lastTransactionAmount:0,
    add: function(itemCost) {
        this.lastTransactionAmount = itemCost;
        this.total +=  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.add('chocolate', 3);

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

Does this line look right to you?


#3

Yes is it wrong?? Oh am I supposed to scan instead of add?


#4

yea that was it wow sorry in the directions it says add 3 of the same so my mind probably just wanted me to put the add method instead of the scan thanks for that.
