[SOLVED]How do I detect this line of code after its done?

I'm not sure what you mean by another piece of code so a few examples:

if true then
	if game.Players.NumPlayers < 1 then
		for i = TIME,1,-1 do
			status.Value = 'Intermission'..i
			wait(1)
		end
		wait(1)
		SpawnPlayers()--this would call on another function
	end
end

if true then
	if game.Players.NumPlayers < 1 then
		for i = TIME,1,-1 do
			status.Value = 'Intermission'..i
			wait(1)
		end
		wait(1)
		workspace.GameScript.Disabled = false--activating another script
	end
end

if true then
	if game.Players.NumPlayers < 1 then
		for i = TIME,1,-1 do
			status.Value = 'Intermission'..i
			wait(1)
		end
		wait(1)
		for _,v in pairs(game.Players:GetPlayers()) do--just going right onto the next thing
			v.Character:MoveTo(Vector3.new(0,0,0))
		end
	end
end
