Hide FBML page to non-fans

Can anyone tell me how to do this?

I've got the generic code:


<fb:fbml version="1.1">
<fb:visible-to-connection>
Fans will see this content.
<fb:else>Non-fans will see this content</fb:else>
</fb:visible-to-connection>
</fb:fbml>

But im not sure what to type in order to reference my exact FBML pages. I tried putting the urls in <a href>, but that dosent work. How do I tell it what FBML tabs I want restricted? please give me a proper example. Thanks.

anyone?
