Why doesn't this work?(I'm trying to add KOs to a table)

	for i,v in pairs(game.Players:GetPlayers()) do 
		t1 = {}
		KO = v.leaderstats.KOs.Value
		 table.insert(t1,#t1+1,KO)			
	end
			table.sort(t1)
				print(t1[#t1])

is part of

local GameModes = {}

function FreeForAll()
	for i,v in pairs(game.Players:GetPlayers()) do 
		Firefox = {}
		zenox = v.leaderstats.Value
		 table.insert(Firefox,zenox, #Firefox + 1)
			table.sort(Firefox)
			print(Firefox[#Firefox])
			
	end
	end

function MultiTeam()
	
end

function Choosemode(Mapchosen)
	if Mapchosen == "Sol2" then
		FreeForAll()
		print("Sol2")
	end
	
	if Mapchosen == "ArenavonOsterreich" then
		MultiTeam()
		print("ArenavonOsterreich")
	end

end




return GameModes

So I'm trying to get the player with the highest KO value right?

Problem is, It's not working,

The highest value of KOs is 5, yet it prints "0" instead No errors in the output.

Help me out here. Thanks in advance
