#1

I have a syntax error in my code can you help me find it please?
var cashRegister = {
total:0,
lastTransactionAmount: 0
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(itemCost){
    this.total -= 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);

At a glance: (a) you're missing a comma after lastTransactionAmount: 0 (b) you should probably change this.total -= lastTransactionAmount to this.total -= this.lastTransactionAmount;
