As a player/parent, if you receive the below message when trying to register you will need to contact the program's organization or event admin:
"You do not have any matching payment plans to choose from. Please contact your organization administrator to complete registration."
The organization or event has most likely not set up a payment plan for your age group and/or gender. You will need to reach out to them to amend this in order for you to continue and complete your registration.
Club Admins can follow this guide: No Matching Payment Plans? Program Registration - as a Club Admin
