Ahh, gotta love them clickbait titles!


The error message returns 'Oops, try again. There is a problem with your syntax'.


var cashRegister = {
    total:0,
    lastTransactionAmount: 0;
    //Dont forget to add your property
    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
    voidLastTransaction: 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.voidLastTransaction();
cashRegister.scan("chocolate", 3);
//Show the total bill
console.log('Your bill is '+cashRegister.total);


#2

Should be lastTransactionAmount: 0,

:slight_smile:


#3

this line:

lastTransactionAmount: 0;

are you certain about this semi-colon? after other member variable and methods you have a different punctuation mark.


#4

:rage: Okay, maybe not.
