[ANSWERED] Attempt to index local 'third' (a nil value)?

Output says "attempt to index local 'third' (a nil value)". How to make this work?

function leaderboard(first, second, third, fourth, fifth, sixth, seventh, eighth)
        return first.leaderstats.Score.Value > second.leaderstats.Score.Value > third.leaderstats.Score.Value > fourth.leaderstats.Score.Value > fifth.leaderstats.Score.Value > sixth.leaderstats.Score.Value > seventh.leaderstats.Score.Value > eighth.leaderstats.Score.Value
    end

    local players = {}
    for _, player in pairs(game.Players:GetPlayers()) do
        if player:FindFirstChild("leaderstats") and
            player.leaderstats:FindFirstChild("Score") then
            table.insert(players, player)
        end
    end

    table.sort(players, leaderboard)

    if players[1] then
        for _, player in pairs(game.Players:GetPlayers()) do
            player.PlayerGui.ScreenGui.Frame.Visible = true
            player.PlayerGui.ScreenGui.Frame.First.Text = "1. " .. players[1].Name
        end
        if players[2] then
            for _, player in pairs(game.Players:GetPlayers()) do
                player.PlayerGui.ScreenGui.Frame.Second.Text = "2. " .. players[2].Name
            end
            if players[3] then
                for _, player in pairs(game.Players:GetPlayers()) do
                    player.PlayerGui.ScreenGui.Frame.Third.Text = "3. " .. players[3].Name
                end
                if players[4] then
                    for _, player in pairs(game.Players:GetPlayers()) do
                        player.PlayerGui.ScreenGui.Frame.Fourth.Text = "4. " .. players[4].Name
-- And So on...
                    end
                end
            end
        end
    end

Thanks!
