Hello, what is wrong?
Error: Opps, try again. false!


Replace this line with your code. 
var cashRegister = {
    total:0,
    lastTransactionAmount: 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;
}
    
};

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransaction();
cashRegister.scan('chocolate', 3);
//Show the total bill
console.log('Your bill is '+cashRegister.total);

in the previous exercise (4. i have to scan it more then once), you had the following instructions:

Scan 4 of each item using your improved scan method

You can't remove this scans, otherwise you can't undo the last transaction. (since there are no transactions)
