Help with GY-521 with Nano 3.0

Sorry for confusing you earlier. I was getting a little frustrated, but now I am doing much better since I started modified the code to fit my needs.

In the next post is the new code that I modified from Jeff's original which is able to display two values that I need for my project. Problem no is that the accelerometer will not display constant values through the buffer and causes a FIFO overflow. I originally used the WORLDACCEL routine, but I was worse than the REALACCEL. What can you suggest to improve this issue?

Also, I understand that on line 196 I could put in code to perform another function, but I wanted to ask where I should code that would be able to transfer the results from the GY to another component? I have code that would transfer information from the Arduino to a Bluetooth transmitter (RN42), but I can't figure out where I exactly I should place it.
