@salemmo409 Hi Salem and thanks for your help! Here is the translation of your information into English:

To save my “langues” field in the User table, I have a workflow: make changes to user → langues = input langues’s value, which works. In my User table, the language appears, and in my “Repas” table, I have a “langues” field of type User. In the UI, to call the data, I used: current page’s table repas’s langue’s langue’s, but it remains empty! Thank you for your help.
