Why are my remote events not firing? (SOLVED)

Okay this is getting annoying lol.

I have a client side script and a server side script. Along with one local script inside a GUI button.

So everything was working before I cut out all of the weapon and armor and health code inside the scripts into my new place where the actual battling is taking place.

So now the only stuff in the scripts are the main menu gui and player data stuff.

For some reason when I did that, my remote events stopped firing to the server. Not sure why! It keeps happening and I keep fixing it with some little thing that changes each time. Not sure if it's a symptom of a bigger problem or what but it's really getting on my nerves cause nothing comes out in the output.

Here is the local script inside my playerCharacterScripts folder: I fire to the server on line 94

-- Sets up Player Components
	local player = game.Players.LocalPlayer
	local Character = player.Character
	local Humanoid = Character:WaitForChild("Humanoid")

	local TweenService = game:GetService("TweenService")
	local RunService = game:GetService("RunService")
	local CoreGui = game:GetService("StarterGui")

	local PlayerData = ReplicatedStorage:WaitForChild("PlayerData")

Here is the Server Module Script inside ServerScriptService:

-- Replicated Storage
	local ReplicatedStorage = game:GetService("ReplicatedStorage")
	local PlayerData = ReplicatedStorage:WaitForChild("PlayerData")
	
-- Services
	local ContextActionService = game:GetService("ContextActionService")
	local TweenService = game:GetService("TweenService")

	-- Tables
		local module = {}
		
		local CustomClass = {
			ClassName = nil,

			Secondary = {},
			Tactical = nil,
			Lethal = nil,
			Perk = nil,
		}

	-- PlayerAdded 
		game.Players.PlayerAdded:Connect(function(player)
			module.AddPlayerData(player)
		end)
		
	-- Adds PlayerData To module
		function module.AddPlayerData(player)
			module[""..player.UserId] = {
				InGame = {
					ArmorAmount = 0,
					MaxHealthPerArmorSlot = 25,
					ArmorSlotsTaken = 0,
					Health = 100,
					MaxHealth = 100,
					MaxAmmo = 30,
					
					-- Holds the weapons table with all of the data.
					WeaponSlot1 = nil,
					WeaponSlot2 = nil,
				},
				
				CustomClasses = {
					CustomClassNumber = 0
				}
			}
		end

-- Custom Loadouts/Custom Classes
--------------------------------------------------------------------------------------------------------
	-- Remote Events
		local NewCustomClass = PlayerData.NewCustomClass
		local CustomClassInfo = PlayerData.CustomClassInfo
		
		-- New Custom Class
		NewCustomClass.OnServerEvent:Connect(function(player)

			module[""..player.UserId].CustomClasses.CustomClassNumber = module[""..player.UserId].CustomClasses.CustomClassNumber + 1
			local CustomClassNumber = module[""..player.UserId].CustomClasses.CustomClassNumber
			CustomClass.Name = "CustomClass"..CustomClassNumber
			
			module[""..player.UserId].CustomClasses["CustomClass"..CustomClassNumber] = CustomClass
			NewCustomClass:FireClient(player, CustomClassNumber)
		end)
		
		CustomClassInfo.OnServerEvent:Connect(function(player, CustomClassName)
			local ClassTable = module[""..player.UserId].CustomClasses[""..CustomClassName]
			CustomClassInfo:FireClient(player, ClassTable)
		end)	

return module

Here is the random local script inside my GUI button in replicated storage that I clone:

local player = game.Players.LocalPlayer

local CustomClass = script.Parent
local CustomClassInfo = game:GetService("ReplicatedStorage").PlayerData:WaitForChild("CustomClassInfo")

CustomClass.MouseButton1Click:Connect(function()
	player.PlayerGui.MainMenu.BackGround.CustomLoadout.ClassSelection.Visible = false
	player.PlayerGui.MainMenu.BackGround.CustomLoadout.WeaponLoadout.Visible = true
	-- Fetch Custom Class Information
	CustomClassInfo:FireServer(CustomClass.Name)
	
	local CustomClassDisconnect = CustomClassInfo.OnClientEvent:Connect(function(ClassTable)

	end)
	CustomClassDisconnect:Disconnect()
end)

That's literally all of the scripts in the place so if there's a problem it's in there lol.

SOLUTION: Since I only had one server script which was a module, it was not being read since nothing required it. So I made a script in serverscriptservice and required it and called one of it's functions when a player spawned in.
