Typically, the Submit button will be grayed out when attempting to submit a partial reversal because the participant is a Team Leader. It is not possible to initiate any reversals or other monetary changes to the participation entry of a Team Leader.  In order to process this partial reversal, another member of the team can temporarily be made Team Leader as follows:
  1. Go to Communities > Special Events > Friends Asking Friends > Kintera Thon
  2. Hover over the event
  3. Click Bookkeeping
  4. Search for another participant who is on the same team as the Team Leader
  5. Click Edit next to their registration entry
  6. Click Edit Registration Information
  7. Click Become a Team Captain of an Existing Team
  8. Choose the team, and Save
 From here, you can now process the partial reversal on the registration entry.  Afterwards, follow the same steps above to reinstate the previous Team Leader.
