What does unexpected symbol near ")" mean?

	   game.Players.PlayerAdded:connect(function(player)
   player.CharacterAdded:connect(function(character)
	 play = game.Players:GetChildren()
	   for i = 1, #play do
	   if play[i] ~= nil then
	   if play[i].TeamColor == BrickColor.new("Bright red") or ("Bright blue") then
	   game.Lighting.LinkedSword:Clone().Parent = play[i].Backpack
	   end) -- This has the red line under it.
	   end)

Hello, thank you for reading.  In the Output Value when I put this code in, it says 'unexpected symbol near ")".  I do not understand and if anyone can help me, I would highly appreciate it.

You need 3 ends before it and you forgot to add BrickColor.new in the if statement.

game.Players.PlayerAdded:connect(function(player)
   	player.CharacterAdded:connect(function(character)
   		  local play = game.Players:GetChildren()
       			for i = 1, #play do
      				 if play[i] ~= nil then
      					 if play[i].TeamColor == BrickColor.new("Bright red") or play[i].TeamColor == BrickColor.new("Bright blue") then
       						game.Lighting.LinkedSword:Clone().Parent = play[i].Backpack
				        end
			        end
		    end
      	end) 
 end)

As a suggestion, this is far much easier:

game.Players.PlayerAdded:connect(function(plr)
	plr.CharacterAdded:connect(function()
		if plr.TeamColor == BrickColor.new("Bright red") 
			or plr.TeamColor == BrickColor.new("Bright blue") then
				game:GetService("Lighting")["LinkedSword"]:Clone().Parent = plr.Backpack
		end
	end)
end)

game.Players.PlayerAdded:connect(function(player)

	player.CharacterAdded:connect(function(character)

	play = game.Players:GetChildren()

	for i = 1, #play do

		if play[i] ~= nil then

			if play[i].TeamColor == BrickColor.new("Bright red") or ("Bright blue") then

				game.Lighting.LinkedSword:Clone().Parent = play[i].Backpack
				
			end
		end
	end
	end)
end)

You forgot a couple of ends mate.
