TypeError: cashRegister.voidLastTransacation is not a function

var cashRegister = {
    total:0,
    lastTransactionAmount:0,
    add: function(itemCost) {

        this.total +=  itemCost;

cashRegister.scan('eggs',1);

//Void the last transaction and then add 3 instead
cashRegister.voidLastTransacation();
cashRegister.scan('chocolate',3);

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

please check your spelling


#3

it was correct,but i just retype--
voidLastTransaction: function() {
and it works...Thanks...


#4

i would have retyped here:

cashRegister.voidLastTransacation();

you given you misspell transaction here


#5
