Getting an error, not sure where it is at the moment. SyntaxError: Expected ':'

var cashRegister = {
    var total: 0,
//insert the add method here    
    add:function(itemCost){
    total+=itemCost;
    console.log(total)
    },
    
    scan: function (item) {
        switch (item) { 
        case "eggs": 
            this.add(0.98); 
            break;
        
        case "milk": 
            this.add(1.23); 
            break;

           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);

Remember to include the context, since total is an instance variable.

this.total += itemCost

Do not log anything in your method.
