why is args[2] nil in this announce script?

local args = script.Parent.Parent.Text:split(" ")

script.Parent.ya.OnServerEvent:Connect(function()
    script.Parent.Parent.Parent.announcemnet.Visible = true
    script.Parent.Parent.Parent.announcemnet:TweenPosition(

        "In",
        "Quad",
        0.4,
        true
        )
    script.Parent.Parent.Parent.announcemnet.yes.Text = args[2]
    
    local blur = Instance.new("BlurEffect")
    blur.Size = 24
    blur.Enabled = true
    blur.Parent = game.Workspace.Camera
    wait(9)
    blur.Size = 23

normal script

local tecks = script.Parent

tecks.FocusLost:Connect(function()
	local args = tecks.Text:split(" ")
	
	if args[1] == "announce" then
		script.ya:FireServer()

end)

local script

i get the error: Players.KoffeKiten.PlayerGui.Yes yes yes.CommandBar.announcemnet.Script:12: invalid argument #3 (string expected, got nil)

There's a lot of things wrong with this. The error is saying that "args" doesn't exist. This is just using a textbox and a button. (this is mostly just an example, it doesn't have any security against exploiters)

playergui:

script.Parent.MouseButton1Click:Connect(function()
	local args = script.Parent.Parent.TextBox.Text
	game.ReplicatedStorage.ya:FireServer(args)
end)

game.ReplicatedStorage.ya.OnServerEvent:Connect(function(plr, text)
	game.ReplicatedStorage.ya:FireAllClients(plr.Name, text)
