Why won't Motor6D's DesiredAngle work?

I'm trying to recover an old Motor6D animation. It uses Motor6D's DesiredAngle property. I fixed and cleaned up the code for FE use, however, the motor's aren't turning at all when the script is ran.

--when the tool is activated, it calls a function which runs this code (theres more, but this is the just of it)
RightShoulder.MaxVelocity = 0.35
LeftShoulder.MaxVelocity = 0.35

RightShoulder.DesiredAngle = -0.8
LeftShoulder.DesiredAngle = 0.8
RightHip.DesiredAngle = 1.57
LeftHip.DesiredAngle = 1.57

All references are from the player's Torso - character's are also set to R6. Are other scripts/animations overlapping thus preventing results to be shown? Is changing these properties even effecting the character?
