Show info on prfile based on CB field value

Hello,

I'm building a userlist with CB 1.7 / Joomla! 1.7. The website has registered users and part of them are classified as 'members'. The CB fields list has a field cb_member (chekcbox) which gets ticked if a person is a 'member'. On the profile pages, I want to show personal info but only want to show some of it to logged-in registered users who are classified as 'members'. So, in other words, I want to show specific info from members to members only. Certain profile info is free for all logged in and registered users, certain profile info is members to members only.

I'm trying to use the [cb:if] function in a text delimiter field to do this as it knows the #me substitution. But as the cb_members field is not a system field, it seems not possible to construct a filter using the #me substitution.

So, how would you construct a display statement that shows (for instance) an email address to a member? I started out with

[cb:if user="#me" cb_member="1"] [cb:userdata field="cb_emailaddress" /] [/cb:if]

but that appears not to work. From the examples I saw here ( www.allmysocials.com/directory/tutorials/item/233-substitution-usage?pop=1&tmpl=component&print=1 ) i and here ( www.joomlapolis.com/forum/77-cb-12-stable-general-discussion-area/93352-cb-content-and-cb-menu#93384 ) gathered the 'user="#me" and the second operator are executed as a logical AND but none of the examples show how a non-system field can be used in the syntax.

Does anyone have a suggestion how to do this ?

Thanks a lot,

Erik
