Move for Rotations in Graphical ROBOTC

I have a new MS team trying to program their bot to move for rotations using quadrature encoders . They are using the graphical version of ROBOTC, which has much less documentation than the text-based version. How should that be set up? They have linked the encoders to specific motors in motor/sensor setup. They have used the forward for rotations block (after resetting the sensor values) without luck. They also tried the moveMotorTarget block. I want to know more so I can give them better guidance. Thanks in advance for your help.
