I get Oops, try again. false but the amount is 8.55 which is correct.


Here is my code

var cashRegister = {
    total: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
    voidLastTransactionAmount: function() {
        this.total -= this.lastTransactionAmount;
        }
};

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

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

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransactionAmount();

cashRegister.scan('chocolate',3);

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

Try without this line before voiding.

Still get the error message

The above is as yet undefined.

voidLastTransaction: 0,
