Motor Refuse to Spin while Testing - What to do?

Hi there currently I am working on a simple skid steer rover using Ardupilot 4.5 but I keep running into the issue of my motors refusing to work within the program itself.

I have been able to make the motors/wheels spin in Basicmicro Motion Studio which is the software used by my motorcontroller of choice a RoboClaw 2x15A controller but when I transition back to MissionPlanner I keep receiving the error “Command was denied by autopilot” while in the Motor Test portion of the Setup window. I’ve looked up my problem and changed around some configs to enable that no safety anything is holding me back.

My controller also works fine while in the calibration window but under Servo Output the values refuse to change no matter how much I push the controls.

I’m at a complete loss at the moment.
