Does anybody know why my queue system code won't work

[thebestrobloxman77 (Tkay)]

Hello, ive been working on a match based game and I needed a queue system I got my scripter to do it and it was working fine until i made an update then it just stopped working after the countdown your not teleported it just sits on 0 and doesn’t tp I checked the place number too

local queue = workspace:WaitForChild("Queue")
local queueContainer = require(game.ReplicatedStorage.ZonePlus).new(queue.JoinCollider)
local teleportService = game:GetService("TeleportService")
local players = game:GetService("Players")

-- Make sure the PlaceId is correct
local teleportPlaceId = 102398531446197 
local countdownTime = 10
local minimumPlayerRequirements = 1
local standardPlayerRequirements = 2

local timer = queue.Screen.Timer
local countdownActive = false
local currentCountdownTask = nil

-- Update queue title based on player count
local function updateQueueTitle()
	local playerCount = #queueContainer:getPlayers()
	queue.Screen.SurfaceGui.Top.Title.Text = "Starting in .. or when full ("..playerCount.."/"..standardPlayerRequirements..")"
end

-- Add player to UI list
local function addTemplate(player)
	local template = game.ReplicatedStorage.UIComponents.QueuePlayer:Clone()
	template.Name = player.Name
	template.Parent = queue.Screen.SurfaceGui.List
	template.PlayerName.Text = player.Name
	template.Image.Image = players:GetUserThumbnailAsync(player.UserId, Enum.ThumbnailType.HeadShot, Enum.ThumbnailSize.Size180x180)
end

-- Remove player from UI list
local function removeTemplate(player)
	local playerTemplate = queue.Screen.SurfaceGui.List:FindFirstChild(player.Name)
	if playerTemplate then
		playerTemplate:Destroy()
	end
end

-- Function to start the countdown
local function startCountdown()
	-- Exit if countdown already active or not enough players
	if countdownActive or #queueContainer:getPlayers() < minimumPlayerRequirements then return end

	-- Start the countdown
	countdownActive = true
	timer.Value = countdownTime

	currentCountdownTask = task.spawn(function()
		while timer.Value >= 0 do
			-- Check if players drop below the minimum required
			if #queueContainer:getPlayers() < minimumPlayerRequirements then
				countdownActive = false
				return 
			end

			-- Update queue title with the remaining countdown
			queue.Screen.SurfaceGui.Top.Title.Text = "Starting in " .. timer.Value .. "s or when full (".. #queueContainer:getPlayers().. "/".. standardPlayerRequirements ..")"
			task.wait(1)
			timer.Value -= 1
		end

		-- After countdown reaches 0, attempt teleport if players are enough
		if countdownActive and #queueContainer:getPlayers() >= minimumPlayerRequirements and timer.Value == 0 then
			print("Countdown finished, teleporting players...")

			for _, player in pairs(queueContainer:getPlayers()) do
				-- Print to debug which players are being teleported
				print("Attempting to teleport player: ", player.Name)

				-- Try to teleport each player
				local success, errorMessage = pcall(function()
					teleportService:Teleport(teleportPlaceId, player)
				end)

				-- Handle teleport success/failure
				if success then
					print("Successfully teleported: ", player.Name)
				else
					warn("Failed to teleport "..player.Name..": "..errorMessage)
				end
			end
		else
			-- Print error if the countdown finished but teleport condition wasn't met
			warn("Teleport attempt failed: Not enough players or countdown was interrupted.")
		end

		-- Reset countdown state after attempting teleport
		countdownActive = false
	end)
end

-- Function to stop the countdown
local function stopCountdown()
	if currentCountdownTask then
		task.cancel(currentCountdownTask)
		currentCountdownTask = nil
		countdownActive = false
	end
end

-- Function to reset the countdown when needed
local function resetCountdown()
	stopCountdown()
	startCountdown() 
end

-- Event when a player enters the queue
queueContainer.playerEntered:Connect(function(player)
	updateQueueTitle()

	-- Add player to queue UI list
	if not queue.Screen.SurfaceGui.List:FindFirstChild(player.Name) then
		addTemplate(player)
	end
	print(player.Name.." has entered the queue!")

	-- Start countdown if minimum players are met
	if #queueContainer:getPlayers() >= minimumPlayerRequirements then
		resetCountdown() 
	end
end)

-- Event when a player exits the queue
queueContainer.playerExited:Connect(function(player)
	updateQueueTitle()
	removeTemplate(player)

	-- Stop countdown if below the minimum player requirements
	if #queueContainer:getPlayers() < minimumPlayerRequirements then
		stopCountdown() 
	else
		resetCountdown() 
	end

	-- If no players are in the queue, reset title
	if #queueContainer:getPlayers() == 0 then
		queue.Screen.SurfaceGui.Top.Title.Text = "Starting in .. or when full ("..#queueContainer:getPlayers().."/"..standardPlayerRequirements..")"
	end

	print(player.Name.." has left the queue!")
end)

Timer.value will not equal zero because your loop breaks runs while it’s greater than or equal to zero

Change the loop to check if it’s only > 0, or change the other part of the code that’s == 0
