Some bugs in this script? How do I fix them?

So in this script, the bugs are that it doesn't team the players on red, and blue when the game starts, and it isn't supposed to ":breakjoints()", it's supposed to just respawn the players without effecting their wipeouts, the game goes by that. Also another bug is that it counts down, and when the game begins, it doesn't remove the message, or hint. So it's harder to see. Could someone help me with this?

Script:

BlueTeam = game.Teams["BlueTeam"]:Clone()
local RedTeam = game.Teams["RedTeam"]:Clone()
local NumPlayers = 2

repeat wait(0)until game:FindFirstChild("Teams")
local GameTime = 250 --5 minutes
local A = game:service('Players')
local A1 = "This service is unavailable, please wait until 1 more player joins..."
local A2 = "Welcome to the official meadows sfing game"
local A4 = "5"
local A3 = "The amount of players is successful, and the game will be starting in" .. A4 .. "Seconds.."
local A5 = "Teaming players..."
local A6 = "Blue team has won"
local A7 = "Red team has won"
local redplayers = 0
local blueplayers = 0
local M = Instance.new("Message",game.Workspace)
local H = Instance.new("Hint",game.Workspace)
local TimeForLoop = .5 --This will loop the script every .5 seconds
local players = 0
local GameRun = false
local GameOver = false
local RegenTeams = false

game.Teams.BlueTeam:remove()
game.Teams.RedTeam:remove()
end

wait(3)
end
end
end

end
end

end
end
end
