Here's a number of non-code related things that could cause a motor not to move:

You didn't enable the robot on the driver station
You didn't plug the PWM cables from the victor to the digital sidecar PWM ports
The PWM cable missed the connector inside the shroud on the victor (this is very easy to do).
You didn't power the digital sidecar
The digital sidecar isn't plugged into the digital module in slot 4 of the cRIO
You have the PWM cables plugged in backwards. B is for black wire.
You have the PWM cables plugged into the wrong PWM ports on the digital sidecar.
The circuit breaker is immediately tripping.
The speed controller isn't powered.
The motor isn't connected to the speed controller.

Knowing what the LED is doing on the speed controller would help narrow down the problem
