[Please help] How would I make a server leaderboard?

Hi, so when I asked a server leaderboard, I mean a real custom leaderboard like in phantom forces where it tells you your leaderstats. I also want the person with the most stats to be on top, but for some reason, when I add a player to the leaderboard it does not show to the other players.

local Players = game:GetService("Players")

local Template = game:GetService("ReplicatedStorage").Template

Players.PlayerAdded:Connect(function(Plr)   

    local newTemplate = Template:Clone()
    newTemplate.Name = Plr.Name
    for i,v in pairs(Players:GetChildren()) do
            if v:FindFirstChild("PlayerGui") then
                if v.PlayerGui:WaitForChild("Leaderboard") then
                    if v.PlayerGui.Leaderboard:WaitForChild("Holder") then
                        if v.PlayerGui.Leaderboard.Holder:WaitForChild("Platform") then
                            newTemplate.Parent = v.PlayerGui.Leaderboard.Holder.Platform
                        end
                    end
                end
            end
    end
    newTemplate.PName.Text = Plr.Name
end)

Players.PlayerRemoving:Connect(function(Plr)
    local server = Players:GetChildren()
    for i,v in pairs(Players:GetChildren()) do
            if v:WaitForChild("PlayerGui") then
                if v.PlayerGui:WaitForChild("Leaderboard") then
                    if v.PlayerGui.Leaderboard:WaitForChild("Holder") then
                        if v.PlayerGui.Leaderboard.Holder:WaitForChild("Platform") then
                            for _,e in pairs(v.PlayerGui.Leaderboard.Holder.Platform:GetChildren()) do
                                if e.Name == Plr.Name then
                                    e:Destroy()
                                end
                            end
                    end
                end
            end
        end
    end
end)
