I'm not sure of I'm too tired to see the obvious, but I cant' get the logic to work as I need:

Members have to be subscribed to either of four different plans, in order for them to get the option to pay for one specific merchandise, which I put as an url link under a menu item.

For each of the four different plans, I've set the "access by menu" for that specific menu item (not top level).

I also set the "Static Conditions on already existing subscriptions" for the merchandise to make sure that one of the four plans is active, before being able to buy the merchandise.

When testing a user without any of the four plans, I'm allowed to get to the menu item without being presented with the four plans. Once on the page for that menu item, the parent level for the merchandise is in place, but the merchandise item isn't (which I guess is correct).

So, why is it possible to get to the menu item, even though no plan is active?

And. maybe the best question is: how should I set this up the easy way?
