I keep getting this error message - SyntaxError: Unexpected token this). what did I do wrong?


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