Why does my player rotate instead of arm

[CreatedInLua (switchhh)]

The player rotates 180 degrees instead of the players arms, I don’t know how to fix this

local RUA = script.Parent.Parent.Parent.Character:WaitForChild("Right Arm")


script.Parent.Equipped:Connect(function()
	RUA.CFrame = RUA.CFrame * CFrame.Angles(math.rad(180), math.rad(0), math.rad(0))
	print(RUA)
end)

Look through the Torso of the Player, then look for the Item Right Shoulder,

That is the Motor6D connecting the Arm to the Torso, from there you can change the Arms CFrame

local RUA = script.Parent.Parent.Parent.Character.Torso:WaitForChild("Right Shoulder")


script.Parent.Equipped:Connect(function()
	RUA.C0 = RUA.C0 * CFrame.Angles(math.rad(180), math.rad(0), math.rad(0))
	print(RUA)
end)

@DasKairo

local RUA = script.Parent.Parent.Parent.Character.Torso:WaitForChild("Right Shoulder")


script.Parent.Equipped:Connect(function()
	RUA.C0 = RUA.C0 * CFrame.Angles(math.rad(180), math.rad(0), math.rad(0))
	print(RUA)
end)

Thank you, it works. The arm is now jiggling up and down as I walk, how do I fix this please?
