Everything works fine in this script. But it does not clone to the players GUI?

So what I am trying to do is, if a admin speaks and says ":givescoreboard (name)" then it would see if that name is valid. But for some reason it does not clone the GUI to the person. Why is that?

local admins = {"dogovpain","RandamuHaise","Player1","6trxshankles9","RoberttOriginal"}
local scoreboardValues = game.Workspace.ScoreboardValues

game.Players.PlayerAdded:Connect(function(plr)
    plr.Chatted:Connect(function(msg)
        if msg:sub(1, 16) == ":givescoreboard " then
        for i = 1,#admins do
        if plr.Name == admins[i] then
        local addPlayer = msg:sub(17, msg:len())    
        print(addPlayer)
        if game.Players:FindFirstChild(addPlayer) then
            print("Player has been found")
            table.insert(admins, addPlayer)
            for i,v in pairs(game.Players:GetPlayers()) do
                if v.Name == admins[i] then
                    if v.PlayerGui:FindFirstChild("ManualGui") then
                    v.PlayerGui:FindFirstChild("ManualGUI"):Destroy() 
                    wait()
                    local manual = script.ManualGUI:Clone()
                    manual.Parent = v.PlayerGui
                end
                end
                end
        else 
            print("Player has not been found")
                end
             end
          end
       end
    end)
end)

game.Players.PlayerAdded:Connect(function(player)
    local playerGui = player.PlayerGui
    for i = 1,#admins do
        if player.Name == admins[i] then
            local manualGui = script:WaitForChild("ManualGUI")
            local cloneGuiToPlayer = manualGui:Clone()
            cloneGuiToPlayer.Parent = playerGui
            if playerGui:FindFirstChild("ManualGUI") then return end
        end
    end
end)
