Change text in a textbox with filtering enabled?

I'm just strugging to make a radio with Filtering Enabled It's a server script.

local PonerMusica = game.Workspace.PonerMusicaGlobal
local PararMusica = game.Workspace.PararMusicaGlobal
local EventoFiltering = game.Workspace.CambiarTexto
Debug = 0

local function PonerMusicaGlobal(p)
    if Debug == 0 then
        Debug = 1
        Audio = Instance.new("Sound")
        Audio.Name = "Audio"
        Audio.Parent = game.Workspace
        local ID = script.Parent.Text
        Audio.Looped = true
        Audio.SoundId = "rbxassetid://"..ID
        Audio:Play()
    end
end

local function PararMusicaGlobal(p)
    if Debug == 1 then
        Debug = 0
        Audio.Looped = false
        Audio:Stop()
    end
end


PararMusica.OnServerEvent:Connect(PararMusicaGlobal)
PonerMusica.OnServerEvent:Connect(PonerMusicaGlobal)
