Can I make my damage script work in an FE game?

function onTouched(hit)
        local human = hit.Parent:findFirstChild("Humanoid")
        local char = hit.Parent
        if (human ~= nil) then
                human.Health = human.Health - 9 
                s = human:LoadAnimation(game.Workspace.dipped)
                s:Play()
                game.Lighting.Boss:Clone().Parent = char.Torso  
                wait(2)
  end
end
script.Parent.Touched:connect(onTouched)

When I put it in a localscript it works but doesn't show damage to other players but when it's a script it has no effect(With FE on) when FE is off it works perfectly for some reason.
