Many thanks. The idea is to then create a candidate list for deletion. The if statement helps fill the list and then we can delete the list in the end. Allin's example works very well. -- Filipe Rodrigues da Costa Send me an email to: filipe(a)pobox.io Reach me through Telegram at: https://t.me/rodriguesdacosta On Fri, 12 Oct 2018, at 14:24, Sven Schreiber wrote:
