We added a probe to the output of the Get Voltage vi, and it just fluctuates around zero (looks like noise) no matter what the potentiometer does. (The pot is in analogue 1, and we identified it as such in the code.)

Thus, if someone has some sample code they would be willing to share, that would be fantastic.

Thanks,

How is the potentiometer connected to the cRIO (ie where is each wire going)? Have you measured the pot's signal with a simple voltmeter to ascertain for certain that it is actually providing a signal?
