Chris. Make your index cards one background type, and your data cards
another. Then use the following scripts in your "Prev" and "Next" buttons,
respectively,

on mouseUp
  go to previous card of this background
end mouseUp

on mouseUp
  go to next card of this background
end mouseUp

This should obviate the need for examining the next card. If there is some
need to have these cards all have the same background, or your examination
process is too complex to render in this fashion, you can always replace
the "send mouseUp ..." with an iterative routine. It may not be as simple
to program, but it should use both time and space a little more efficiently.
