You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    Fix the error, and make the script function properly.
  2. What is the issue? Include screenshots/videos if possible!
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?

Script:

function gamemain()
	_G.Winners = {} --clear/reset table

	FadeInOutMusic(music.Lobby,music.Winner)
	
	for i = 15, 1, -1 do
		game.ReplicatedStorage.Remotes.Text:FireAllClients('Intermission [ '..i..' ]')
		wait(1)
	end
	
	local Maps = game.ServerStorage.Maps:GetChildren()
	local Map1Chosen = Maps[math.random(#game.ServerStorage.Maps:GetChildren())] -- line giving the error
	local Map2Chosen

Can you be more precise? Which line is the one throwing the error?

math.random don’t accept just 0, as an argument.

math.random(value)

is a sugar syntax of

math.random(1, value)

thus it returns an error as argument 1 cannot be larger than argument 2.
I suspect #game.ServerStorage.Maps:GetChildren() returns 0.
and, btw, you can do #Maps instead of #game.ServerStorage.Maps:GetChildren().
(Repeating until for this isn’t a good idea as random values are unpredictable, thereotically, this could go on forever, I suggest you create an array, of numbers then get the value from the array, then remove that value)

Did you even call the function “gamemain”?
