Cloning script not working?

So this is in a game script I am making for a game. For some reason, it only works once in the beginning of the first round, but won't work in the second round.

Output gave me nothing and I have no idea what is the problem. Can someone please help me? Here's the script:

--[[
All of the variables and such are defined. I will only be posting the ones that I suspect are part of this issue.
--]]

local back = game.ServerStorage:WaitForChild("BackUp")
local clone = back:clone()
local time2remove = game.Workspace:WaitForChild("Item")

function Respawn()
	time2remove:destroy()
	wait(0.01)
	clone.Parent = game.Workspace
	clone.Name = "Item"
end

while wait() do
	if NewGameMustStart.Value == true then
		NewGameMustStart.Value = false
		msg.Parent = game.Workspace
		msg.Text = "Welcome!" 
		wait(3)
		msg.Text = "A new game is beginning! Sit tight!"
		wait(3)
		msg.Text = "Game Beginning!"
		wait(2)
		Respawn()
		GameOn.Value = true 
		msg:destroy()
	end
end --- There's more to this script, but I'm only posting the parts that matter in this issue.

You never set NewGameMustStart.Value back to true. You set it to false in the beginning, but then at the end of the script, you changed GameOn.Value to true. Since NewGameMustStart.Value is left at false, the condition statement is false and the loop never runs a second time.
