It says that newpos is a member data of class 2. Classes are templates. In order to use it, you must create an instance.
(It wouldn't make sense if you could actually change the throttle, in say, an engine template, would it?)
You'd have to create an instance of class 2 and then modify its data.
It would be a good idea to check class tutorials (they are available on the site).

Or perhaps you actually intend to make newpos a static method?
