BLEEP BLEEP - Oops. Try Again. False

I keep getting the error in the title. Here's my code:

var cashRegister = {
total:0,
//Dont forget to add your property
lastTransactionAmount: 0,

add: function(itemCost) {
    this.lastTransactionAmount = 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
voidLastTransactionMethod: 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.voidLastTransactionMethod();
cashRegister.scan('chocolate', 3);

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

my result is this:

Your bill is 8.55

I got it.
The name of the method is voidLastTransaction
But you have typed the name of the method as voidLastTransactionMethod

I keep getting an error i really don't understand why

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;
    //this.lastTransactionAmount = 0;
},

};

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);

A small typo, voidlastTransaction should be voidLastTransaction.
