game.Players.PlayerAdded:Connect(function(plr)
    if Workspace.StarterItemsUpgraded.StarterMonitorUpgraded.ScreenGui.Enabled == true then
        wait(math.random(1, 2))
        plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + 1 
    elseif plr.leaderstats.Followers.Value >130 then plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + math.random(1,2) 
    elseif plr.leaderstats.Followers.Value >250 then plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + math.random(1,3)
    elseif plr.leaderstats.Followers.Value >350 then plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + math.random(1,4) 
    elseif plr.leaderstats.Followers.Value >410 then plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + math.random(2,4)
    elseif plr.leaderstats.Followers.Value >500 then plr.leaderstats.Followers.Value = plr.leaderstats.Followers.Value + math.random(2,5)
