At first I didn't know what that even means but after bit of searching on Internet I learnt that apparently I'm using variable that hasn't been declared first therefore program doesn't understand what it is. But I can't find undeclared variable or variable that's misspelled.


var cashRegister = {
    total:0,
    lastTransactionAmount: 0,
    
    //Dont forget to add your property
    add: function(itemCost) {
        this.total +=  itemCost;
        this.quantity = quantity;
        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
    var 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);

That's not what it says :confused: what are you googling for? Use the error message as a search term. This is just another syntax error, so google also for how to find that.
