I was following a tutorial by AlvinBlox and it says I did something wrong. Help?

I was trying to make a simple Roblox game with a tutorial from AlvinBlox and it keeps saying the following message: "ServerScriptService.MainScript:27: Expected identifier when parsing expression, got ')'" And when I try to fix it: "ServerScriptService.MainScript:82: Expected 'end' (to close 'do' at line 27), got "

I followed everything he said to do in the tutorial (https://www.youtube.com/watch?v=1MappXJ51Oo) so I can't figure out what I did wrong! If any of you can help me fix my game and not have to restart, I would greatly appreciate that.

P.S-I have already tried to rewrite the line, it won't work. EDIT: My main script is here (down to my issue, line 27):

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ServerStorage = game:GetService("ServerStorage")

local MapsFolder = ServerStorage:WaitForChild("Maps")

local Status = ReplicatedStorage:WaitForChild("Status")

local GameLength = 300



while true do
	
	Status.Value = "Waiting for enough players"
	
	repeat wait() until game.Players.NumPlayers >=2
	
	Status.Value = "Intermission"
	
	wait(15)
	
	local plrs = {}
	
	for i, player in pairs (game.Players:GetPlayers()) do
			if player then
				table.insert(plrs,player)

local ReplicatedStorage = game:GetService("ReplicatedStorage")

local ServerStorage = game:GetService("ServerStorage")

local MapsFolder = ServerStorage:WaitForChild("Maps")

local Status = ReplicatedStorage:WaitForChild("Status")

local GameLength = 300

while true do
	Status.Value = "Waiting for enough players"

	repeat wait() until game.Players.NumPlayers >=2

	Status.Value = "Intermission"

	wait(15)

	local plrs = {}

	for i, player in pairs (game.Players:GetPlayers()) do
        	if player then
            		table.insert(plrs,player)
		end
	end
end

I did the same exact tutorial. My game worked. You forgot to add end marks at the end of the for loop. End marks are very important for loops like for and while do. Hope this works!
