Bonjour, merci pour la promptitude.
Cependant, mon souci demeure.
En fait dans le questionnaire, je dispose des informations suivantes: jour, mois et année. Je souhaite calculer l’âge à partir de ces trois variables distinctes comme dans le fichier que je joint.
Merci

Pourqoui ne pas outilser calendar type. (and Required No)? And a rule/hint like if month not known, take June. If day not known take 15.
With our design, you will need to make a lot of checks against invalid calendar dates, like 31 November or 29 February 2021.
To convert, you could concat your part to the KoBo/ODK standard date text format yyyy-mm-dd and convert the string with date () function. (See XLSForm documentation).
date text format).
Before you would also need to define calculation for a missing element, e.g. if no day take 15. Date types cannot have missing elements.
