Restrict access to certain pages but not others

Hi, I am using Membership for the first time and watched all the videos. I cannot get URL groups to work the way i want and read docs.

URL blocking does not work at all unless I set ... "Use membership level" to "None"

However then ALL pages to my site are blocked, not just the URLs I want.

I still want people to see the home page and blog whether they are logged in or not.

I want to restrict access to certain pages to only those people who are logged in (regardless of their access level).

I'd be very grateful for help.
