I'm having a "group" problem

[Len Morgan]

I'm sorry to keep coming back with what must seem like stupid 
questions.  This one has me really confused.

I've created a group that contains summary information in a small band 
that goes on each card.  I have set the behavior to "background."  There 
is a field filled in on the first card (where I created the group in the 
first place).

When I created a second card, the group does get added to the card but 
when I switch between the two cards, the summary data on each card 
(which is part of the group) is different!  I thought the group (when 
set to act like a background) would not only carry the design of the 
group but the contents of the fields too.  Is this not correct?
