As the error says, your application can't find the controller method to which your route maps.

Unfortunately you haven't provided any information about the controller: class name, location, namespace, methods, how its loaded, etc. so it's not possible to see where this is going wrong. Nor do you tell use which of the route triggers the error and which, if any, work.

I've not seen the "impactController.itinerary" syntax before, but the other approaches should work provided the Controller is properly named and loaded.

You may also want to try running "php artisan routes" to see which routes your application is recognising.

Hi petercoles thanks for your comment, have made some adjustments to the code showing methods available in my controller. have changed "impactController.itinerary" to "impactController@itinerary".
