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

cashRegister.scan('eggs',1);
cashRegister.scan('milk',1);
cashRegister.scan('magazine',1);
cashRegister.scan('chocolate',4);
cashRegister.voidLast();//Void the last transaction and then add 3 instead
cashRegister.scan('chocolate',3);
//console.log(cashRegister.lastTransactionAmount);
//Show the total bill
console.log('Your bill is '+cashRegister.total);

I don't know what is wrong!?!? Help!
