Repstore = game.ReplicatedStorage
maps = Repstore.Maps:GetChildren()

    while true do       
        if game.Players.NumPlayers > 1 then
        for i, v in pairs(game.Players:GetChildren()) do

            pgui:WaitForChild("MainText").TextLabel.Text = "Not enough players to start!"
        end
        else
            for i, v in pairs(game.Players:GetChildren()) do
            pgui1 = v:WaitForChild("PlayerGui")
            pgui1:WaitForChild("MainText").TextLabel.Text = "Chosing map"
            wait(3)
            ranGame = math.random(1, #maps)
            gameChosen = maps[ranGame]
