Single servo control from MaxMSP - js and serial problems

hi,

i am trying to control a servo via serial port - i am using the ArduinoServo example from here: http://www.mdhosale.com/md_arduino/ i am getting the message in Max 'js: no function bang' when i start it - and the serial communication does not happen. i am a beginner, so any help on how to get rid of these errors would be very appreciated.
