Why won't the code in my remote event run?

(I made a custom leaderboard)

I have created a remote event that runs everytime a player leaves or joins the game. I added a script which adds the player to the leaderboard, but the code won't run. No errors come into the console either.

Local Script

local ReplicatedStorage = game:GetService("ReplicatedStorage")
local RemoveRemoteEvent = ReplicatedStorage:WaitForChild("LeaderboardRemovePlayer")
local AddRemoteEvent = ReplicatedStorage:WaitForChild("LeaderboardAddPlayer")

game.Players.PlayerAdded:Connect(function()
    AddRemoteEvent:FireServer()
end)

game.Players.PlayerRemoving:Connect(function()
    RemoveRemoteEvent:FireServer()
end)

Server Script

local ServerStorage = game:GetService("ServerStorage")
local Players = game:GetService("Players")
local Teams = game:GetService("Teams")
local RE = game:GetService("ReplicatedStorage"):WaitForChild('LeaderboardAddPlayer')


RE.OnServerEvent:Connect(function()
    for i,v in pairs(Players:GetPlayers()) do
        ServerStorage:WaitForChild("PlayerThing").Parent = v.PlayerGui:WaitForChild("Leaderboard"):WaitForChild("PlayerList")
    end
    RE:FireAllClients()
end)
