Events + and Membership. Can't get Prices to work.

Hi,
I'm using Events+ to set up paid events. I also have 3 levels of membership on the site. I'm trying to make it so that people with Membership pay a different price, however on the front end it is only showing the default price and doesn't seem to be changing. I've tried changing my user role on the admin bar but nothing happens!

I want to be able to display all four prices. So non users can see the benefits of subscribing. Any idea where I'm going wrong?

Thanks.
