Why is this Event manager script not working?

This script is supposed to manage events and execute functions

However, the script doesn't work, and I don't know why. Output didn't give me anything.

Can someone please help me?

There's two scripts involved.

Here's the one that reacts to events when they are fired:

local Players = game.Players

local Events = game.ReplicatedStorage.Events
local CaptureFlag = Events.CaptureFlag
local ReturnFlag = Events.ReturnFlag
local GUI2Change = game.StarterGui.Notifier.Frame:WaitForChild("Text")

function OnCaptureFlag(player)
	game.ServerScriptService.Score.Value = game.ServerScriptService.Score.Value + 1
	local player = game.Players:getPlayers()
	GUI2Change.Text = "The flag has been captured!"
	for i = 1, #player do
		player[i].PlayerGui.Notifier.Frame.Text.Text = "The flag has been captured!"
	end
end

local function OnReturnFlag(flagColor)
	local player = game.Players:getPlayers()
	GUI2Change.Text = "The flag has been returned!"
	for i = 1, #player do
		player[i].PlayerGui.Notifier.Frame.Text.Text = "The flag has been returned!"
	end
end

CaptureFlag.Event:connect(OnCaptureFlag)
ReturnFlag.Event:connect(OnReturnFlag)

and here's the one that actually fires them:

local FlagStandManager = {}

-- ROBLOX Services
local Players = game.Players

-- Game Services
local Configurations = require(game.ServerStorage.Configurations)

local FlagObjects = {}
local FlagCarriers = {}
