Topic: Agile Web Development with Rails / The Depot Application

I have a problem when i want to delete the last user. It works even if i get a message that the last user can not be deleted. Is it possible that the problem comes from that line

if User.count.zero? rais “cant delete last user”
end

should it not be

if User.count.zero+1? rais “cant delete last user”
end

Thank you
