5/7 Unexpected identifier error


#1

I checked out the Q&A forum and still couldn't debug this. I'm running into a syntax error:

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;
}

};

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

cashRegister.voidLastTransaction();
cashRegister.scan('chocolate',3);

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

lastTransactionAmount: 0 //Add a comma at the end of this line!

God, they even warned me to add a comma and I didn't. Thank you!
