Vector 3 expected, got Cframe?

local clickdetector = script.Parent.ClickDetector
local replicatedstorage = game:GetService("ReplicatedStorage")
local Scare = replicatedstorage.JumpScareFile.MOVINGSCARY
local noise = script.Parent.Parent.Noise

clickdetector.MouseHoverEnter:Connect(function(plr)
	local player = game.Workspace:FindFirstChild(plr.Name)
	script.Parent.Parent:Destroy()
	local copy = Scare:Clone()
	copy.Parent = workspace
	local noisecopy = noise:Clone()
	noisecopy.Parent = player

	for i = 1, 29 do
		wait(0.1)
		copy.Position = CFrame.new(copy.Position + Vector3.new(1, 0, 0)) -- issue

		if i == 1 then
			noisecopy:Play()
		elseif i == 28 then
			noisecopy:Destroy()
		end
	end

	copy:Destroy()
	script.Parent.Parent:Destroy()
end)

Im not too sure how to change position so I looked up how to and the code I have is what it said. If anyone could help that would be appreciated.

Try changing the beginning of the line from copy.Position to copy.CFrame and see if it works.
