Why wont this script, for group rank only teams work??

adminTeam = game.Teams:findFirstChild("Engraved Voids") 

function onEntered(newPlayer) 
if newPlayer:IsInGroup(1086850) and newPlayer.GetRankID <= 3 then
newPlayer.TeamColor = adminTeam.TeamColor 
end 
end

I don't know what's wrong with this script, could somebody fix it please?

game.Players.PlayerAdded:connect(function(player)
	if player:GetRankInGroup(1086850) >= # then -- put number where # is
		player.TeamColor = BrickColor.new("teamcolorhere") -- or you could do what you did in 			your script, although I prefer this method
	end
end)

that might work, I'm not sure how GetRankID would work (or if it exists?)
