Bonjour,
J’ai un souci appsheet me communique le numéro de la ligne plutôt que la colonne demandée lors de l’envoi automatique du mail, alors que lors de la présentation du formulaire tout est ok.
dans mon cas Numéro de dossier.
Savez-vous d’où cela peut venir ?
Merci de votre aide.
Bonjour Julien
Il vaut mieux poser les questions en anglais pour s’assurer d’avoir une réponse rapide 
Translated question:
"Hello,
I have a problem with appsheet giving me the line number rather than the column requested when the email is sent automatically, whereas when the form is submitted everything is ok.
In my case the file number.
Do you know where this can come from?
Thank you for your help."
Can you show us the template you use ? Screenshot are best.
Basically, row ID are used. You may need to use a dereference expression to show the column content.
For reference:
Hi @Julien44350
You may also want to hide the name of the person here on your screenshot 
This is a label issue, then.
In your table, on the app editor, you probably ticked one column as being the label property of your table.
This means it will be this column content that will be shown proeminently, such as in dropdown lists.
You can build another label column, or tick another column as being the label.
Here for example, I concatenated the first name and last name together using a virtual column.
