Why does this vote for map script give me an string expected error? [Closed]

I am making a vote for map gui but suddendly it gave me an error i do not know how to fix or where it is cause the error is in the gamescript but it errors on a RemoteEvent line so it's in another script but i do not know where here are the scripts

Game Script

local allmaps = {1,2,3}

-- Main game code
math.randomseed(tick())
local ss = game:GetService("ServerStorage")
local rs = game:GetService("ReplicatedStorage")
local stats = workspace.GameStats
local inPlayPlayers = {}

function Intermission()
	stats.InProgress.Value = true
	if workspace:FindFirstChild("Map") then
		workspace.Map:Destroy()
	end
	stats.GameStatus.Value = "Intermission"
	for i = 5,0,-1 do
		wait(1)
		stats.SecondaryMessage.Value = i
	end
	
	
	local map = game.ServerScriptService.ChooseMap.Choose:Invoke(allmaps)
	game.ReplicatedStorage.RoundEvent.MapChosen:FireAllClients(map)
	
	workspace.GameStats.GameStatus.Value = "Loading Map"
	
	game.ServerStorage.Maps[map]:Clone().Parent = workspace
	
end

function getReadyPlayers()
	local players = {}
	for _,v in pairs(game.Players:GetPlayers()) do
		--if v.Data.Playing.Value == true then
			table.insert(players,v)
		--end
	end
	return players
end

while true do
	if workspace.GameStats.InProgress.Value == false then
		if #getReadyPlayers() < 1 then
			stats.GameStatus.Value = "Waiting for players"
		else
			Intermission()
		end
	end
	wait(1)
end
