What is wrong here?

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("eggg");
cashRegister.scan("eggs");
cashRegister.scan("magazine");
cashRegister.scan("magazine");
caseRegister.scan("magazine");

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

@lake529,

Have a close look at

"eggg"

And see "caseRegister.scan"
