Hello, since the new Player Model is running (R15)... i don't have idea about how to change Shoulders CFrame without errors, so can anybody help me?

I'm trying to convert a R6 Script in R15 script.

Before

RArmJoint = Character.Torso:FindFirstChild("Right Shoulder")
LArmJoint = Character.Torso:FindFirstChild("Left Shoulder")
RHipJoint = Character.Torso:FindFirstChild("Right Hip")
LHipJoint = Character.Torso:FindFirstChild("Left Hip")

After

RArmJoint = Character.UpperTorso:FindFirstChild("RightShoulderRigAttachment")
LArmJoint = Character.UpperTorso:FindFirstChild("LeftShoulderRigAttachment")
RHipJoint = Character.UpperTorso:FindFirstChild("RightCollarAttachment")
LHipJoint = Character.UpperTorso:FindFirstChild("LeftCollarAttachment")

But, when i start the game, i got errors.

end

Please, help me!
