what error ? it's a lot easier to help if you include the traceback. > Now XPLMGetDataf should be returning float. should be ? have you verified this ? try adding print self.ACphi, type(self.ACphi) value = XPLMGetDataf(self.ACphi) print value, type(value) before the cos_phi line, and let us know what it prints. > Is there something that I'm completely missing about how Python does > tyonig or something? not necessarily, but you may need to work a little on your trouble- shooting skills (rule 1: when in doubt, use print. print is your friend). </F> -- http://mail.python.org/mailman/listinfo/python-list
