I'm not sure if I am doing this "Transform" thing right. Can anyone help me?

I recently discovered about Motor6D.Transform. When I first heard of this, I decided to go to studio and test it out.

local function Transform(joint,cframe,time)
	joint.Transform = joint.Transform:lerp(cframe,time)
end

game:GetService("RunService").Stepped:Connect(function()
	Transform(RightShoulder,CFrame.Angles(math.rad(20),0,0),.5)
	Transform(RightElbow,CFrame.Angles(math.rad(120),0,0),.5)
	Transform(RightWrist,CFrame.Angles(math.rad(10),0,0),.5)
end)

But after running it, it did not seem to work..

If anyone could help me, I would really appreciate it.

There are no errors in the output if you are wondering.
