What is wrong here? Tornado v6.0 dragger script

I need to do a wind limit, to where location maximum he can drag (not suck, dragging, suck comming soon), and only the positive X maximum is working, it's not dragging to his center the negative X position and Z position.

The maximum wind to drag is the maxd, accordding the fujita escale.

local force = script.Parent.Parent.Configuration:FindFirstChild("Fujita escale")
if force.Value == 0 then
	local wind = 4
else
	local wind = force.Value * 100
end
script.Parent.Mesh.Scale = Vector3.new((wind * 10) + 700,script.Parent.Mesh.Scale.Y, "-"..(wind * 10) + 700)
local maxd = wind / 2
local maxs = wind / 3
	contagemdesons =  wind / 10
local atual = 1
repeat
	local clone = script.Tornadowinds:clone()
	clone.Parent = script.Parent
	local atual = atual + 1
	wait()
until contagemdesons - 1 < atual
script.Tornadowinds:remove()
script.Parent.Sounds.Disabled = false
script.Parent.Spin.Disabled = false
local childlist = {}
local force = script.Parent.Parent.Configuration:FindFirstChild("Fujita escale")
if force.Value == 0 then
	local wind = 25
else
	local wind = force.Value * 100
end
local maxd = wind / 2
local maxs = wind /3
