Cframe is not a valid member of Part?

plr.CharacterAdded:connect(function(char)

	local humanoid,hrp = char:WaitForChild("Humanoid"),char:WaitForChild("HumanoidRootPart")
	
	wait()
	
	if humanoid and hrp then
		if stage.Value ~= 0 then
			
			local part = workspace.ObbyStages:FindFirstChild(stage.Value)
			hrp.Cframe = part.Cframe + Vector3.new(0,1,0)

I've put in the code above and it gives me the following Error:

"Cframe is not a valid member of Part"

Any clues of what it might be?

Notice that you need to cap the "f" in CFrame.
