[PD] pd crashes when using expr

[Tina Shah]

hi list, i'm trying to use the expr object in my little app to figure out 
the range of incoming h values (hsv) - i.e.- if ($f1 > 0 && $f1 < 0.05, 1, 
0);  right now i have 9 of these types of if statements.  when running the 
program things don't work properly.  pd crashes when i go to edit the expr 
part or when i destroy the gem window.  also while running the app i get 
these errors:
error: expr: ex_eval: unexpected type 0
expr: bang: unrecognized result 881328160
the file attached is the file i'm working with.  please let me know if 
anyone has any ideas of what might be wrong.  i'm using windows xp, pd .39-2 
and gem .90.

thanks!
