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

voidLastTransaction: function(){
    this.total = this.total - this.lastTransactionAmount;
    };

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

};

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);


#2

voidLastTransaction: function(){
    this.total = this.total - this.lastTransactionAmount;
}; // should be , instead ;

#3

is it in the wrong spot. looks like same code


#4
    }
    return true;
},
//Add the voidLastTransaction Method here
voidLastTransaction: function(){
    this.total = this.total - this.lastTransactionAmount;
    };

};

IM LOST


#5

You have syntax error after voidLastTransaction method - you used " ; " (semi-colon) but you need to use " , ":

voidLastTransaction: function(){
    this.total = this.total - this.lastTransactionAmount;
}, // it's correct (here you used ; instead ,);

In my previous answer I showed you where you have an error and in comment section I said how it should be.
