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!
