NOTE: If the names and numbers do not match you can click the box "I prefer to be under a different Sponsor and Enroller. " Then go back to their TEAM PAGE and double check their number.  If you still get the wrong number and name showing up, stop the sign up process and get in touch with your friend right away so they can help you.  Their contact information will be on their profile page.
