Form is being received with empty answers

I created a form for my website, and when I test it, and fill all the blanks, all I have in responce is a blank sheet with all my question, but not my answers. 
I don't know why it doesn't take my answers, the 2 only thing there are in the response sheet is the remark and the pictures that the user added. 

My website is not yet online, but it is due soon, i'm working for someone on the creation of the site. 
But here is a screenshot of the responce sheet. 

 

Sorry for my english 

Based on your screenshot, I see this is about your form 62434023107342, named Formulaire de demande.

I have taken a look at your previous submissions, and I do see you have several almost blank/empty submissions. I see that your questions are not marked as required, which means that your form can be submitted without your users entering any information into such fields.

Please first ensure that any mandatory questions on your form are marked as required, in a way depicted on the following image:

Even when your form fields are marked as required, if you use conditional logic to hide them, your users will be able to submit your form without filling out these fields. These is so because a hidden field cannot be filled, so as soon as one of your show/hide conditions is matched and it hides a field - any field that it hides is no longer technically required.

What this means in practice is that you should not use questions to hide your Form Collapse tools in the way you have them set up at the moment, because your users will be able to submit the form without selecting anything else except for "Suivant" options.

If you want your users to fill out one section at a time, you may want to use a Page Break field instead of the Form Collapse tool, and disable your show/hide rules. With a Page Break, your users can only proceed to the following page once all the required fields have been filled on the current page of the form. You can add them as depicted below:

Here is how your form would appear and function with Page Break fields instead of the Form Collapse fields:

If you need any further assistance, or experience any troubles with your required questions being submitted empty, please let us know. Thank you.

I don't know if you are going to read this, but it was exactly the problem.
Thanks a lot !
