My arduino code works. with the serial port. The processing code connects to the arduino but the data is not registering. Thank you for any…

I I think I see the problem.
char receivedChars[numChars]; is 4 bytes. an int is only 2 bytes so dataNumber = atoi(receivedChars); does not work; How to do that?
