--declare variables

	local randomMode = math.random(0,1)

	local check0 = true
	local check1 = false

-- initialize components
 function render()
	clearToLoad = true
	Console.TextScaled = true
	clear(Console)
	init()
end

function clear(text)
	text.Text = ""
end

 function loadGame()
	Console.Text = "No errors yet! :D"
	Console.Text = Console.Text .. '\nPlease wait at least 5 seconds for loading \nbefore clicking a button.'
	if (OnlineButton == script.Parent.Frame.OnlineButton) then
	elseif (check0 == false) then
		check0 = true
		check()

end

		wait(8.5)
		clear(Console)
	end
	clear(Console)
end

function noLoadPermissions(Perm)
	if (Perm == false) then
		Console.Text = Console.Text .. '\nUnable to load! error code 06, something is \n unable to confirm! Contact AlienMister! \n'
		wait(8.5)
		clear(Console)
		loadGame()
	end
end
	
function init()

end
--Now for the code and calling these functions
print 'start'
loadGame()
OnlineButton.MouseButton1Click:connect(PlayGame("online", true, false))
	StoryButton.MouseButton1Click:connect(PlayGame("story", true, false))
	RandomModeButton.MouseButton1Click:connect(PlayGame("random", true, true))

ps i also added in prints in random areas, no matter what though, i still get the same error, i know that it does not get passed through loadgame and it goes strait to playgame even if i havent clicked a button. AND I did put render on top now but same thing.
