The parameter with the callback shows whatever you return from the callbackfunction. But you may transfer computed results to other parameters.

But be careful: you shouldn't keep references to poser objects (actors, parameters). Poser can kill these references at any time! And as a result you get pretty much everything from weird behavior to crashes.

This is especially true for callback functions. A lot can happen between calls. Therefore it is highly advisable to always get the references "fresh". Even if this seems awkward at first glance: You are on the safe side this way.
