Chronoforms obtain a value from db with dropdown

Hi, i've a form and a DB read function that load two column azienda and email from a db table; with azienda field it populate a dropdown that names cliente.
Now i've the necessity to save on a hidden field the value of field email that correspond to selected value of cliente in the dropdown.
How i can make it possible?

Thanks

Hi parsifaltheking,

The simplest way is to use the client name (or id) to look up the email after the form is submitted.
