Short term memory, can't find the error


#1

This is my code:

var cashRegister = {
total: 0,
//insert the add method here
add: function (itemCost) {
this.total += itemCost;
},

scan: function (item) {
    switch (item) { 
    case "eggs": 
        this.add(0.98); 
        break;

    case "milk": 
        this.add(1.23); 
        break;

    //Add other 2 items here
    case "magazine":
        this.add(4.99);
        break;
    case "chocolate" :
        this.add(0.45);
    break;

    }
    return true;
}

}

//Scan 2 eggs and 3 magazines
cashRegister.scan("egg");
cashRegister.scan("egg");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
//Show the total bill
console.log('Your bill is '+cashRegister.total);

I just can't find the error... can anyone help me?
(Btw the error is: Oops, try again. Have you scanned eggs twice and magazine three times?)


#2

Are you scanning "egg" or "eggs"?

Thank you so much, I was searching for years for any mistake, now it's working :wink:
