I believe the best way you could explain what Versa points are and what they are for
is that
Point"1" Versa points are for how your RANK is achieved
Point "2" You could tell them that they are a reward,for the Sales and Actions that they do,just by doing the To Do List Daily they receive 1 vp{reward point} per action
The more Sales or Actions the more Vp Points {Rewards} they will recieve
