3. Short-Term Memory Urgent


#1

Would somebody illuminate me with what is the problem with my code? It seems just fine but...


https://www.codecademy.com/courses/close-the-super-makert/0/3?curriculum_id=506324b3a7dffd00020bf661#

I get "Oops, try again. "Calling cashRegister.add(3.2) set the cashRegister.total to NaN instead of 3.2"

var cashRegister = {
    total: 0,
    add: function(itemCost) {
       this.total += this.itemCost;
},
    
    
    scan: function (item) {
        switch (item) { 
        case "eggs": 
            this.add(0.98); 
            break;
        
        case "milk": 
            this.add(1.23); 
            break;
        
        case "magazine":
            this.add(4.99);
            break;
            
        case "chocolate":
            this.add(0.45);
            break;
        
        
        }
        return true;
    }
};

cashRegister.scan("eggs");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
cashRegister.scan("eggs");
cashRegister.scan("magazine");//Scan 2 eggs and 3 magazines

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

HI this method

add: function(itemCost) {
    this.total += this.itemCost;
}

you should remove the this. to itemCost this line

this.total += this.itemCost;

because itemCost is the parameter of the method add
