5/7 SyntaxError: Unexpected token

Anything wrong here?
var cashRegister = {
total:0,
//Dont forget to add your property
add: function(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.scan('chocolate',3);

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

I think you exactly highlighted where your problem was.

}; //Take this semi-colon out.

#4

That actually did not work


#5

You need to do these two things:
1. add your property.
2. Modify your add method.

Your code should look thus:

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

This should work.
