Hi there, i have make another hidden field ![grafik](https://us1.discourse-cdn.com/flex020/uploads/elfsight/original/3X/6/4/6445a314b71adce66d5c022c714415d20c88aea2.png) Otherwise I couldn’t get the ID in the email. Field ID: [uniqueid] is empty in the email. The Field ID [total] will be sent to the email. I can’t explain why this is so So far so good. @Max If you use the generated ID to create a continuous sequence of numbers in which the current date may also be hidden, you could use it as a ticket ID.
