Hello all, so the result is right( the bill comes out to 8.55) but its returning a "Oops. Try Again. false" error. What am I doing wrong in my code?

// Write your code below!

var cashRegister = {
    total: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
    voidLastTranscation: 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.voidLastTranscation();
cashRegister.scan('chocolate',3);

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


#2

the method has to be named voidLastTransaction, you misspelled the method name


#3

this is not the solution


#4

It is the Solution!

See your code with correct method name runs


#5

Sorry for my maybe harsh first reaction.

Please show us your code and i try to help


#6

Yeah, that is the solution. You misspelled the method name in two places. Transcation instead of Transaction.

@lothar82, codecamedy1337 is not the person who made the original topic. So codecamedy1337 might have a different problem altogether then datawhiz86973

This is a good example why it is annoying to "hijack" a topic...

Ah yes, i see it now. Well, he confused me if no one else :slight_smile:
