Hi,
In order to loop through cards of just a single background do the 
following

on mouseUp
  repeat with a = 1 to the number of cards in this background
    go to next card in this background
  end repeat
end mouseUp

The key is "card in this background"

PS It will probably take me a few postings to figure out 
this "posting business"
