Trying to make a Shout out System for Chatbox and I can't seem to figure out how to see if the DataStore has been updated with new Values? 

local Datastore = game.ReplicatedStorage:WaitForChild("Datastore")
local DS = game:GetService("DataStoreService"):GetDataStore("ShoutData")
local DoneShout = false
	
local data2 = Datastore:InvokeServer("Get",nil)
			local empty = {
			Subject = "",
			Player = "",}
			empty.Subject = "Testing Hello Test2"
			empty.Player = "Kuzx"
			table.insert(data2,1,empty)	
			table.remove(data2,250)
			Datastore:InvokeServer("Set",data2)
	
while wait(5) do
	
	local data = Datastore:InvokeServer("Get",nil)
	for i,v in pairs(data) do	
	if DoneShout == false then
	DoneShout = true
	local message = Instance.new("StringValue")
	message.Value = "[Shout] "..v.Player..": "..v.Subject
	local check = Instance.new("BoolValue",message)
	wait(0.5)
	message.Parent = script.Parent.ServerMessage
	end
	end
	
	DoneShout = false
	end

This is only a short code I try to write to see if the Message is being sent, Now I just need help with getting a function to run the Shout. Any ideas or pointing out some hints would be great

I did try to use OnUpdate but this is only when a value is being updated so this doesn't help me when I'm trying to add a Value to the DataStore and updating it to the Chatbox.
