FF Remover not working? [SOLVED, THANKS FOR HELP]

I wouldn't suggest using supercoolguy's method as the ForceField might not always exist. Instead, this code would not break:

script.Parent.Touched:connect(function(touch)
    if touch.Parent:FindFirstChild("Humanoid") and touch.Parent:FindFirstChild("ForceField") then
        touch.Parent.ForceField:remove()
    end
end)

Try this:

function ff(part)
    local h = part.Parent:findFirstChild("Humanoid")
    if h then
        h.Parent.ForceField:Destroy()
    end
end
script.Parent.Touched:connect(ff)

The reason it isn't working is because ForceField isn't a child of Game, but the ForceField is a child of the Humanoids parent. Place this into a part.
