Configuring the Membership Plugin

I am trying to set up the Membership plugin. I have been through the entire PDF but it is still not working.

Essentially what we need is for the entire site to be visible to all visitors EXCEPT for one page:

So people will sign up for a two week trial, and after 2 weeks, they will be charged on a weekly basis. Every week, the content on the link above will change... with an email being sent as a notification to subscribers.

In the Access Levels, I've set up Positive Rules for the one page... and Negative Rules for the same page in the Visitors Level.

The page is still fully viewable without redirecting to the Subscription page.

Can you please advise how to remedy the situation?
Thank you!
