I have the following data on my screen but the filter does not work, I can’t understand what’s wrong ![Capture d’écran 2021-08-21 à 13.55.56](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/4/5/454284c5ba0bde079c98aafbf04779e6fcba55dd.jpeg) ---

You would want to try a joined list of emails instead of a lookup. I’m not sure “is included in” works with array items like that. ---

It works with a joined list of emails thanks. “Is included” not working for a list was a bit misleading I guess though ---
