how would i get the players name without it being blank? (server script)

##so i have a function with returns a string for a message to be put out when the game ends but i just dont know how to get the username of the player. (thing with elseif gamemode==2 then)

#function (the lines i wanna focus on are 22-28)

function getWinningTeamString()
	local red = 0
	local blue = 0

	local players = game.Players:GetChildren()
	local a = 0
	
if gamemode == 1 then
	for i=1,#players do
		if (players[i].TeamColor == game.Teams:FindFirstChild("BLUE TEAM").TeamColor) then
			if (players[i]:FindFirstChild("leaderstats") and players[i].leaderstats:FindFirstChild("Kills")) then
				blue = blue + players[i].leaderstats:FindFirstChild("Kills").Value
			end
		end

		if (players[i].TeamColor == game.Teams:FindFirstChild("RED TEAM").TeamColor) then
			if (players[i]:FindFirstChild("leaderstats") and players[i].leaderstats:FindFirstChild("Kills")) then
				red = red + players[i].leaderstats:FindFirstChild("Kills").Value
			end
		end
	end
	elseif gamemode==2 then
	for i=1,#players do
		if (players[i]:FindFirstChild("leaderstats") and players[i].leaderstats:FindFirstChild("Kills")) then

		end
	end
end
	

	if gamemode==1 and (red == blue) then return "Stalemate! (Nobody won...)" end
	if gamemode==1 and (red > blue) then return string.format("Red defeated the opposition by %d points!", red - blue) end
	if gamemode==1 and (red < blue) then return string.format("Blue defeated the opposition by %d points!", blue - red) end
	
	if gamemode==2 then
			return "The winner is "..value1(username).." with "..value2(kills).." kills!"
	end 
	
	end

#where this function is used is here (line 14):

while true do
	players = game:GetService("Players"):GetChildren()
	repeat wait(1) do end until #players>=2
		gamemode = 2--math.random(1,2)
	if gamemode==1 then
		gamestart(mapstorage.TDM:GetChildren())
	elseif gamemode==2 then
		gamestart(mapstorage.FFA:GetChildren())
	end
	wait(game_length-30)
		messageEvent:FireAllClients("30 seconds left until the end of this round!",5)
		script["30seconds"]:Play()
	wait(30)
		messageEvent:FireAllClients(getWinningTeamString(),30) -- right here btw 
-- i cut off the rest since theres no point in displaying it
