How to input data on success?

How to input data on success?

Okay, so I need to automatically add data to a field called "Supervisor" from a reference field "Location_Subscribed_to1.Supervisor".   And then I need to add data to a field called "Group_Manager" from a form called "Location_Subscribed_to1.Group_Manager" and I cannot figure out how to do it on my life.  So please help me!

Thanks,
Michael McNeill
