Comment faire pour qu'une personne voit son nombre de réponse juste sur un formulaire ?

Hi fumey,

Thank you for reaching out to Jotform Support. Please allow me to answer your language in the English Language. Our French support is not available at the moment. However, If you prefer to receive help in your native language, please let us know and we'll forward your ticket to our French Support Team. 

I believe you are trying to create a quiz form type. If yes, then you can use the Quiz Form App with the help of this user guide. Kindly make sure to enable the "Show Results to the user after submission." so that the result will appear after hitting the Submit button.

Give it a try and let us know how it goes.
