Whats wrong with my code

[ItzGamerzZA (bear)]

so the code works normal until round time finishes when it does the timer just starts going in the negative numbers instead of starting over

local RS = game:GetService("ReplicatedStorage")

local uiChangeEvent = RS.Events.Remote.UiRoundEvent

local Time = game.ReplicatedStorage.RoundData.Time
local ball = workspace.Lobby.ball
local redTeam = game.Teams.RedTeam
local blueTeam = game.Teams.RedTeam
local player = game.Players.LocalPlayer
local Players = game:GetService("Players")
local Client = Players:GetPlayerFromCharacter(player)
local Teams = game:GetService("Teams")
local teams = Teams:GetTeams()

--SETTING--
local ITimeBeforeTeleport = 10
local IPreparingTime = 10
local IRoundTime = 10
local IChooseMapTime = 10
--END--

local TimeBeforeTeleport = ITimeBeforeTeleport
local RoundTime = IRoundTime
local PreparingTime = IPreparingTime
local ChooseMapTime = IChooseMapTime

function giveTeamCoins(teamColor,amount)
	for i,v in ipairs(game.Players:GetChildren()) do
		if v.TeamColor == BrickColor.new(teamColor) then
			v.leaderstats.Coins.Value = v.leaderstats.Coins.Value + amount
		end
	end
end

function killPlayers()
	for _, player in pairs(game.Players:GetChildren()) do
		local char = player.Character
		if char:WaitForChild("Humanoid").Health > 0 then
			char:WaitForChild("Humanoid").Health = 0
		end
	end
end

while true do
		Time.Value = ITimeBeforeTeleport
		RS.Events.Remote.Intermission:FireAllClients(player, nil)

		repeat -- intermission
			task.wait(1)
			Time.Value -= 1
			TimeBeforeTeleport -= 1
		until TimeBeforeTeleport == 0


		TimeBeforeTeleport = ITimeBeforeTeleport
		Time.Value = IChooseMapTime
		RS.Events.Remote.VotingTime:FireAllClients(player, nil)
	
		repeat -- Voting
			task.wait(1)
			Time.Value -= 1
			TimeBeforeTeleport -= 1
		until TimeBeforeTeleport == 0

		ChooseMapTime = IChooseMapTime
		Time.Value = IPreparingTime

		workspace.SpawnLocation.Position = Vector3.new(60.489, 1.75, -16.019)
		workspace.SpawnLocation.Transparency = 1
		workspace.SpawnLocation.Decal.Transparency = 1
		
		wait(0.5)
		killPlayers()
		task.wait(0.1)
		RS.Events.Remote.PrepTime:FireAllClients(player, nil)

		task.wait(1)
		
		workspace.SpawnLocation.Position = Vector3.new(-91.107, 48.081, -17.446)
		workspace.SpawnLocation.Transparency = 0
		workspace.SpawnLocation.Decal.Transparency = 0
		task.wait(0.1)

		repeat -- preptime 
			task.wait(1)
			Time.Value -= 1
			PreparingTime -= 1
		until PreparingTime == 0

		PreparingTime = IPreparingTime
		Time.Value = IRoundTime

		ball.Anchored = false
		ball.Transparency = 0
		ball.Velocity = Vector3.new()
		ball.AssemblyAngularVelocity = Vector3.new()
		RS.Events.Remote.RoundTime:FireAllClients()
	
		repeat -- round time
		task.wait(1)
		Time.Value -= 1
		RoundTime -= 1
		until RoundTime == 0

		RoundTime = IRoundTime
	

		killPlayers()
		ball.Anchored = true
		ball.Position = Vector3.new(60.366, 7.596, -16.019)
		ball.Velocity = Vector3.new()
		ball.AssemblyAngularVelocity = Vector3.new()
		ball.Transparency = 1
end

Never do == but rather <= or >= because numbers aren’t perfect integers and can go below your target number even 0.000000000001 floating points! but it wouldn’t stop the loop if it isn’t perfect

EDIT: grammar
