Answer
Good morning!
Thank you for visiting allexperts.com

ROTATIONAL ERROR
This is the USAV's phrase for what I've always called "serving out of order".  So, of course, a rotational error occurs when the wrong girl is serving.  If you wish, I can tell you what happens if the error is caught immediately, or if the error is caught after 6 points are served, or if the error is caught a few minutes after the wrong server's serve is broken and the other team has served.  

POSITIONAL ERROR
This is the USAV's phrase for what I've always called an "overlap".  A team is guilty of a rotational error when, at the moment of serve, the players aren't in their proper order, 1 through 6.  Does that help?  If not, please contact me and I'll be more specific.

IMPROPER REQUEST
This is a phrase that is used when the coach requests to do something that he/she cannot.  For example, I request putting Jill in for a MB.  YIKES, Jill already went into the game as an OH.  Improper request.  Another example is when I try to call a 3rd timeout.  Another example would be when I try to make a sub when I've already reached the maximum # allowed.
