How do you get one players name copied only once instead of twice in different slots?

--What I've been trying to do is get one players name and have it only copy the username **once ** from a specific team

--Here's my code it initiates the script upon ":start"
-- :start FULLplayername
game.Players.PlayerAdded:connect(function(player)
	player.Chatted:connect(function(chat)
		local msg = string.lower(chat)
		print(player.Team)
		for i,v in pairs(game.Players:GetPlayers()) do
			if msg == string.lower(start) .. string.lower(v.Name) then
				if player.Name ~= v.Name then
					game.Workspace.RemoveEvents.StartPlayer:FireAllClients(player, v.Name)
					game.Workspace["_Screen"]:FindFirstChild("Screen"):FindFirstChild("Display"):FindFirstChild("plr_1"):FindFirstChild("plr_Username").Text=v.Name
					game.Workspace["_Screen"]:FindFirstChild("ScreenTwo"):FindFirstChild("Display"):FindFirstChild("plr_1"):FindFirstChild("plr_Username").Text=v.Name
				end
			end
		end
	end)
end)

Can anyone please help? I need it to get the users name only once instead of copying it twice from and to another column.
