|In this step, you need to select who is attending. A "GUEST" is one of your children. You must have already added your children to your profile first. "ME" is you... the parent.
For your first registration, you should select "ME+" and then the number of children that are signing up for this particular program. You can see this option highlighted below with a red box.
For your second and any registrations after that, select "No me, but I'm registering" and select the number of athletes for that program.
Finally, if you have forgotten to select the parent registration earlier, just click "Me Only" and then proceed.
