It may be that you have accidentally created a Registration Page that is Paid instead of Free. A Registration Page enables people to add themselves (with your approval) as Members of your booster club. To create a Free Registration Page:

• Navigate to Webmaster > Pages > Add New.
• Select Registration Page in the add page wizard.
• Add the Page name and select the navigation option you would like.
• Click Save and the page is created.
• In Webmaster you can then click on the Page to enter it. The Page comes in a default format with basic information fields.
• To include additional information fields, click the Add Fields edit icon on the right side.
• Select Free or Paid registration. If you select Free, you can then enter the description and instructions. (If you select Paid, it will be looking for a specific Membership Product from the Store.)
• Choose the option for family members to be added as Members or Non-members.
• Add any type of field already in existence in People, and choose to make the field required or optional.
• Add all the fields you would like, then click Save.
• The Registration Page is now available to publish on the website by using the Save and Publish icon at the top right.
