How to fix this bug in this script?

[Turbe$Z]

When me and my friend press '2', the script show double answer (- 1 - 1 instead of -2) or when me press '1' and my friend press '2', the script show this: 1.) Answer1 - 1 - 0 and 2.) Answer2 - 1 - 0.. How to fix this? Sorry for my bad english.

code:

--client--

local szavon = false --is this something used to prevent double questions? it should be serverside :/
local ido = 30
local valasz = 0 
local valasz2 = 0
-- I need an explanation of valasz and valasz2, if you use them to keep track of the selected answer then there are errors
GUIEditor_Window = {}
GUIEditor_Label = {}

function szAblak(ker,v1,v2) --question, answ1, answ2, all strings
	if not szavon then 
		local v_1 = v1 --answ1, useless variable

		local szavon = true

		local sw,sh = guiGetScreenSize() 

		GUIEditor_Window[1] = guiCreateWindow(sw/1.48,sh/1.4,sw/3.2,sh/3.6,"Szavazás",false) --wow it's hard to me thinking relatives coord like this, wouldn't be % much easier?

				end
			end, 1000,30)

	--v1 1 or 0, v2 2 or 0. BOTH CAN BE 0!!!! ALSO BOTH CAN BE 1 AND 2. The font wans't already set? you are not changing any passed var serverside. This doesn't make sense
