Mini game Teleport script won't work along with count down script why isn't it working?

local s = script.Stat t = 0 while true do t = 15 repeat t = t-1 s.Value = "Game Starts in..."..t wait(1)

until t == 0
s.Value = "Game Starting"
wait(2)
local plrs = game.Players:GetChildren()			

for i = 1,#plrs do
	local num = math.random (1,8)
	plrs[i].Characters.Head.CFrame = CFrame.new(game.workspace.Teleports["Parts"..num].Position)
end
	t = 100
repeat
	t = t-1
	s.Value = t.."Time Remaining"
	wait(1)
	
until t == 0

end
