How Do I Convert This onTouched Script To Filtering Enabled?

So this script is placed into a coin where when a player touches the coin, he collects it and removes the coin. It does however work in studio.. but when I go in game.. It doesn't work. Each coin is called "Coin". Here is the code.

function onTouch(hit)

    if (script.Parent.got.Value == false) then 
    check = hit.Parent:FindFirstChild("Humanoid")

    if check ~= nil then 
    script.Parent.got.Value = true
    script.Parent.Mesh.Scale = Vector3.new(0,0,0)

        local user = game.Players:GetPlayerFromCharacter(hit.Parent)
        local stats = user.PlayerGui:findFirstChild("Stats")

        if stats ~= nil then 
            local cash = stats:findFirstChild("Coins")---change to money currency
            user.PlayerGui.Stats.Coin.Value = user.PlayerGui.Stats.Coin.Value+1
            local audio = Instance.new("Sound")
            audio.Parent = script.Parent
            audio.SoundId = "http://www.roblox.com/asset/?id=420163794"
            audio:Play()
            wait(1)
            audio:Destroy()

        end 

    end 
    end 
end

script.Parent.Touched:connect(onTouch)
