View that shows fields of the og nodes

hello everybody,
i am sorry to ask but i am a bit desperate right now.
my problem is i dont know how to tell views to access organic group cck fields properly and show it in a block,
i am trying to build a view that displays 3 fields that people need to fill out if they create a group.
to this view i want to add a block display and show it only on the group pages.
on each group page it shall display the value users typed in when creating the group.
i am not reaaly sure how i shall tell views to do exactly that. i experimented quite a while with the arguments and relationships
but i was not able to figure it out.
i would really really appreciate your help.
thanks you!
