George,
Sorry for not getting back sooner on this, but there are a few things keeping me "on the go" at the moment.
Have you tried selecting "Add Motion to Library" to see if you can run the action using the Right mouse pop-up menu afterwards on this character?
The information available on the various page links
here suggest that everything "should" work as per your actions, however maybe you missed a step somewhere along the way. I would start with trying the Add Motion to Library option first to see if that works.
