Error in bleep


#1


cashRegister.voidLastTransaction is not a function


Replace this line with your 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
    voidLastTransactionAmount(){
        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);


#2

here:

 voidLastTransactionAmount(){
        this.total=this.lastTransactionAmount;
        this.LastTransactionAmount=0;
    }

you named the method voidLastTransactionAmount, it should be voidLastTransaction


#3

#4

can i see an updated version of your code?


#5

The definition of your voidLastTransaction() is wrong. Read the question calmly and digest it. You can do it
