why doesn't my model move using cframe?

local rep = game:GetService("ReplicatedStorage")
local pc = rep:FindFirstChild("PC")
local clickd = script.Parent.ClickDetector
clickd.MouseClick:Connect(function()
	if rep and pc then
		pc:Clone()
		pc.Parent = workspace
		pc.CFrame = CFrame.new(128.681, 3.926, 40.64)
	end
end)

this script is parented to a part with a click detector inside of it everything works just fine until the script reaches the CFrame part i know it's about the model im trying to move i guess im not doing it properly any help is apriciated
