Hi,

On page https://www.gnds.fr/preprod/sondage.html  button "Terminer" is on activated.

Here's the message in Chrome Console :

Uncaught TypeError: form.ajaxSubmit is not a function

    at Object.CjSurveyApi.submitAjaxForm (cj.surveys.min.js?v=1579067405:1718)

    at HTMLButtonElement.onclick

Let me know if you need super user credentials.

Many thanks for your help.

Regards.
