What the heck am i doing wrong??

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

cashRegister.scan('eggs',4);
cashRegister.scan('milk',4);
cashRegister.scan('magazine',4);
cashRegister.scan('chocolate',4);

cashRegister.voidLastTransaction();
cashRegister.scan('chocolate',3);

//Void the last transaction and then add 3 instead

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

@cortbaker,
You forgot to mention,
that you were presented with a
TypeError: stating that the voidLastTransaction Method was not defined

Now try to find the voidLastTransaction-property in your cashRegister-object.....

===============================

To get a pass
you will have to use

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);

cashRegister.voidLastTransaction();
cashRegister.scan('chocolate',3);
