Creating database using two collections - Syntax error

I try building a database with two collections, one customer collection and one for orders. I get the following error:

Script Error {

        return Model;

                if (!_.contains(Object.keys(attrs),"lastName"))
                    return "Error: attributes do not contain lastName";
 
                for (var key in attrs) {
                    var value = attrs[key];
                    if (key === "lastName") {
                        if (value.length <= 0) {
                            return "Error: No lastName!";
                        }
                    }
                }
            }
 
        });
 
        return Model;
    },
    extendCollection: function(Collection) {        
        _.extend(Collection.prototype, {
            // extended functions and properties go here
 
            comparator : function(customer) {
                return customer.get('lastName');
           }
        });
 
        return Collection;
    }
}

First I created the customers database, then I added the orders database. Deleting the sql- database and deleting the App from the iPhone Simulator did not help.
