I have a team door, but its not running when i do this?

So I made a team only door, and I want the 'Building Station [2]' team to be able to go through, and my other team 'Citizens' to not be able to go through, and every time I go through immediately after touching the part to be put on the 'Building Station [2]' team, it lets me go through, but when I touch the door while being a citizen, then become a 'Building Station [2]' member, then touch the door it does not work. Anybody know how to fix this? Thanks.

wait()
local team = game:GetService("Teams")["Drilling Station [2]"].TeamColor
local db = false
function onTouch(hit)
	if db == false then
		db = true
    if game.Players:GetPlayerFromCharacter(hit.Parent) ~= nil then
	if game.Players:GetPlayerFromCharacter(hit.Parent).TeamColor == team then print(hit.Parent.Name.. "is a allowed inside the factory because he is in the " .. game.Players:GetPlayerFromCharacter(hit.Parent).Team.Name.. " Team.")
		workspace.RedBit.BrickColor = BrickColor.new(177, 229, 166)
		script.Parent.Transparency = 0.5
		script.Parent.CanCollide = false
		 workspace.press:Play()
			wait(2)
		 script.Parent.Transparency = 0.2
		script.Parent.CanCollide = true
	workspace.RedBit.BrickColor = BrickColor.new(255, 89, 89)
	wait(1)
		db = false
		return
			end
		end
	end
end
script.Parent.Touched:Connect(onTouch)
