Why does it say this? How do i fix it?

local function splitplayers()
game.Teams.Lobby:Destroy()
local UseSeccondTeam = false
for i, v in ipairs(_Players:GetChildren()) do
	if  UseSecondTeam then
		v.TeamColor = 
		_Teams["Cops"].TeamColor
	else
		v.TeamColor = 
		_Teams["Robbers"].TeamColor
	end
		UseSecondTeam = not UseSecondTeam
end
end

There is a blue underline under if** UseSecondTeam** then and it says UseSecondTeam is only used in the enclosing function consider changing it to local
