I really need help identifying what am getting wrong here.
Spent hours and not able to debug this.

I keep getting
Your Bill is 10.35

ooops try again, false.

Here is my code:

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

You've missed an 'r' out of 'Transaction.'
