NumPlayer script not working?

This is a local script inside the StarterGui. Idk why its not working as I have revised this code several times.

repeat wait() until game.Players.LocalPlayer.PlayerGui.Menu.Main.plr

local plrstart = 2
local roundinsession =  false
local plr = game.Players.LocalPlayer
local plrgui = plr.PlayerGui
local char = plr.Character
local curplr = game.Players.NumPlayers
local gamestart = false

repeat
	wait(1)

if curplr<plrstart then 
	plrgui.Menu.Main.plr.Visible = true
	if plrstart-curplr ==1 then
		leftplr = plrstart-curplr
	plrgui.Menu.Main.plr.Text = "You need " ..leftplr.. " more Player(s) to start"
	print"not enough plrs"
	
	
	elseif leftplr>1 then
			plrgui.Menu.Main.plr.Visible = true

			plrgui.Menu.Main.plr.Text = "Enough Players."
		plrgui.Menu.Main.plr.gamestart.Value = true
		print"enough plrs"
		
		
	elseif leftplr==0 then
			plrgui.Menu.Main.plr.Visible = true

			plrgui.Menu.Main.plr.Text = "Enough Players."
		plrgui.Menu.Main.plr.gamestart.Value = true
		print"enough plrs"

	
	end
end

until
plrgui.Menu.Main.plr.gamestart.Value == true
