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
