Bleep, bleep ... unexpected identifier


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


//Void the last transaction and then add 3 instead
cashRegister.scan('chocolate', 3);

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


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.


Finding this website quite useful .... it tells where is a bug
