Ok, I think I follow that, except I am not sure how to write it.
I want to place a paypal button with a yrly subscription for 2 individuals by ID #, but, I want to give them access to the same level one content as a regular level 1 member, on the same page as the other paypal buttons. But, I don't want anyone but them to see it. Which is why I would use the simple shortcode conditional by user id. I had already created the paypal button and it works. I don't know how to write the conditional for a user id.
I am not giving them access to something different on the site, I am just giving them a different payment plan. So then, I don't know how to write the custom capability for this.
I want them in the system so I don't have to guess from year to year what or when or how they are covering their membership.
Thank you in advance for your help.
