No responses... Maybe I should be more clear.
The basic question is, is it possible to provide access to the same restricted content by more then one membership?
It seems as though the two different membership levels cancel one another out, unless the user purchases BOTH memberships.
For example, I would like Silver members to have access to Types of Clubs.
I would like Gold Members to have access to Types of Clubs AND Types of Restaurants. For some reason, unless the user buys BOTH the silver and gold membership, they cannot view Types of Clubs. If they purchase only a silver the cannot view Types of Clubs. If they purchase only a Gold, they cannot view Types of Clubs, but they can see Types of Restaurants.
I'm using CMS Extensions access depending on subscription: URL Parts.
