Help on this clone then movement script?

u said

clone = game.Lighting.Arrow:clone()

then use it, not

move = script.Parent.Parent.Arrow

u dont need that line, use 'clone'

clone.CFrame

cos I don't see u using the Variable clone :/

function onTouched(hit)
     if hit.Parent:findFirstChild("Humanoid") then -- Verify that a actual player hit it
local clone = game.Lighting.Arrow:clone()
    clone.CFrame = CFrame.new(-8.5, 3.5, -0.5) --See? u didn't need the Variable 'move' just use the Cloned Part as the Part, else it's not used yet, cos u gotta give it it's Parent and stuff...
clone = script.Parent -- Object Tree location of part
    speed = .1 -- Speed of the movements, the lower the number, the faster and more smooth
    distance = 10 --The distance to move along the axis
    timestorun = distance * 10 -- Times to run, don't change this as it allows for smooth transitions
    for i = 1, timestorun  do -- i represents the index or current position of the loop, it starts at one and goes to whatever the times to run is, meaning it will run that many times
        wait(speed) -- Wait for the designated speed time
        game.Workspace.part.CFrame = CFrame.new(game.Workspace.part.Position + Vector3.new(0.1,0,0)) -- Change the CFrame by 0.1 to allow for a smooth transition
    end -- End the loop
    end -- End the first function
    end
script.Parent.Touched:connect(onTouched)

else if the 'part' is the Arrow then

script.Parent.Touched:connect(function(hit) --It's better to have it this way if ya need to remove the Arrow later
     if hit.Parent:findFirstChild("Humanoid") then
local clone = game.Lighting.Arrow:clone()
    clone:MoveTo(Vector3.new(-8.5, 3.5, -0.5)) --I use MoveTo for Models
    clone.Shaft.Rotation = CFrame.new(ur Angles here)
clone.Parent = script.Parent
    speed = .1
    distance = 10
    timestorun = distance * 10
    for i = 1, timestorun  do
        wait(speed)
        clone.RocketPropulsion:fire() --Find the cloned Arrow's RocketPropulsion and Activates it
    game.Debris:AddItem(clone, 10) --Change clone to other Names if u ever need to, change 10 to Seconds in how much it's removed
    end
    end
    end)

In an Arrow

local RP = Instance.new('RocketPropulsion', script.parent)
RP.Target = game.Workspace.locater1 --change to ur Part Name if u changed it...
RP.MaxSpeed = 1000 --Change to ur Speed
RP.CartoonFactor = 0 --this is for the Arrow Pointing forward to the Target, change to ur needs if 0 doesn't suit u...
