Script isn't working in online mode?

Everything works in Play Solo and the gui shows up fine, but when I tried it in online mode, nothing worked. Here's the code:

players = game.Players:GetPlayers()
local timeleft = Workspace:findFirstChild('time')
local piece = Workspace.teleportationpart
local map = Workspace.Map
current = {}
 
function removeTime()
        for i = 120, 0, -1 do
                wait(1)
                timeleft.Value = i
        end
end
 
function gameStart()
        for i, v in pairs(players) do
                local stats = v.PlayerGui.fullGui.everything.gamePlay.informer
                stats.Text = 'New round beginning!'
                stats.FontSize = 'Size24'
                timeleft.Value = 120
                wait(1)
                stats.Text = ''
        end
        teleportPlayers()
        countdown()
        removeTime()
end
 
function teleportPlayers()
        for i, v in pairs(players) do
                if v.play.Value == true then
                        v.Character.Torso.CFrame = CFrame.new(piece.Position+Vector3.new(
                                math.random(1,10),
                                math.random(2,6),
                        math.random(1,10)))
                        table.insert(current, v.Name)
                end
        end
end
 
function countdown()
        for i, v in pairs(current) do
                local stats = game.Players:FindFirstChild(v).PlayerGui.fullGui.everything.gamePlay.informer
                stats.Text = '3'
                wait(1)
                stats.Text = '2'
                wait(1)
                stats.Text = '1'
                wait(1)
                stats.Text = 'Begin!'
                stats.FontSize = 'Size48'
                wait(2)
                stats.Text = ''
                wait(1)
                stats.Text = 'Objective: Find a weapon. '
                stats.FontSize = 'Size36'
        end
end
 
function endGame()
        for i,v in pairs(current) do
                current[i] = nil
        end
end
 
function waitSome()
        for i, v in pairs(players) do
                local stats = v.PlayerGui.fullGui.everything.gamePlay.informer
                stats.FontSize = 'Size24'
                stats.Text = "Let's take a quick break. Use this time to buy stuff in the shop!"
                wait(30)
                stats.Text = ''
        end
end
 
while wait() do
        gameStart()
        endGame()
        wait(1)
        waitSome()
end
