Configuring customer authorization little trouble

[simpledomaining]

I have 1.5.1 version of zen cart.
i am trying to make customer to register/login/get authorized by store owner and then see prices (wholesale store). When i try to do that using configure> customer details>customer shop status - view prices and products 2
and configure>customer details>authorization pending 2, if i am not logged on and i click on one of categories to see products i see product images, product names and word null in place of prices under every product. how can i fix this?
thanks.

A link to your site, please.

The reason I asked for a link to the site is because when I set those options exactly as you did in my stock Zencart test site using the Classic template, I see 'Login for Price' where the price would be, which I assume is what you want. First thing I would do is switch to the Classic template (if you have installed a custom one) to see if it works then.
