Bleep Bleep (5/7): error despite correct(?) result (SOLVED)


#1

e: Nevermind, found the error. Had to write voidLastTransaction instead of voidlastTransaction...

Hey everyone!

I'm stuck at exercise 5 of 7 aka Bleep Bleep:
https://www.codecademy.com/courses/close-the-super-makert/0/5?curriculum_id=506324b3a7dffd00020bf661

I can get the console to print 8.55 as my total which should be the correct price if I did the math correctly. So everything is working as it should. However, when I try to submit I get the 'Oops, try again. false'-error. But I can't figure out why.

My code:

var cashRegister = {
    total:0,

    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;
    },

    voidlastTransaction: function() {
        this.total -= this.lastTransactionAmount; 
    }
};

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

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

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

Thank you!
