Protected Content on Coursepress and Another Landing Page

Ok, so I think I have it set up correctly, Can you please check? - I've given support access.

How do I get a button or link where they can sign up for it? So I can send it to people for them to sign up once I finish it?

Also...

The other question... since this is a subsite and my landing pages are on my main site, does that mean I can't put the payment button on my main site landing page? I will have to recreate the landing page on this site so I can have the enrollment button on this site? Or is there a way for me to get a payment button code to put on my main site where the landing page is?
