I have this site: http://hardthaus.de/feinschmeckertermine/sos-kinderdorf/
here you can make a booking for a dinner. In the form I have a hidden field called "Date of event" or in German "Datum des Feinschmeckertermines" in all posts I have a Custom Field called event_date
in my hidden field I check Allow field to be populated dynamically
and set Parameter Name: event_date
but no data are transmited to e-mail, there I have {all_fields} so it must be visible.
what am I doing wrong here?
It think it was working a few month ago, now I came back on the site for updates and it found the mistake....
