Chronoform v5 in joomla 3.4.4 not inserting data

Hello,

I make a form. All information is sent by email, but data are not stored in the database. This is not the first form I create with chronoforms v5, so I think the problem must come from the environment. I use Joomla 3.4.4 with chronoform v5, but the site was initially in Joomla 2.5 with chronoform v4.

Here are some screenshots as attachments.

Thanks in advance

Thank you very much Bob, that was the problem.
I guess this is the first time I store the id in the database.
