I'm making a tycoon that when you buy an item the parts float into place. This is a script that gets cloned into each brick. But I cant figure out what's wrong

function Effect(Part)
	local OldPos = Part.CFrame
	local Num1 = math.random(2,5)
	local Num2 = math.random(2,5)
	local Num3 = math.random(2,5)
	local Rot1 = math.random(1,180)
	local Rot2 = math.random(1,180)
	local Rot3 = math.random(1,180)
	local Pos = OldPos + Vector3.new(Num1,Num2,Num3)
	local FullPos = Pos * CFrame.Angles(math.rad(Rot1),math.rad(Rot2),math.rad(Rot3))
	Part.CFrame = FullPos
	for i = 1,100 do
		wait(1)
		local NewPos = FullPos - Vector3.new(FullPos.X-Num1/100,FullPos.Y-Num2/100,FullPos.Z-Num3/100)
		Part.CFrame = NewPos
	end
end

Effect(script.Parent)

Thankyou
