Why isn't my DataStore working? [CLOSED]

I'm currently trying to create a Cross-Server-Chatting to find out what's possible using DataStores. But now I'm meeting an error that is making no sense to me. This here is a ModuleScript in ServerStorage called "Chat". It's simple and I'm seeing no mistake in it.

local Chat = {}

Server = game:GetService("DataStoreService"):GetDataStore("Server")

function Chat:SMTS(msg,client)
	local continue = true
	local n = 1
	while continue == true do
		print("continuing")
		if Server:GetAsync("MSG."..n) ~= nil then
			print("another one!")
			n=n+1
		elseif Server:GetAsync("MSG."..n) == nil then
			print("stopping")
			continue = false
		end
		wait()
	end
	print("Time to send the message to the server!")
	Server:SetAsync("MSG."..n, "["..client.."]: "..msg)
end

return Chat

Now I've been testing this entire thing a few times already, but it's always doing the same: Nothing. There's no error shown or so, but also nothing like printing or text changing. I've ended up confused about what's wrong and am in need of some proffessional help. Thanks in advance!

You're only returning a table value on line 23, you're not actually calling the function.

Change line 23 to return Chat.SMTS()

Move your script to ServerScriptService
