Hi, code newbie here.
Is there a way to auto-generate a serial number, or id with configured letter/number sequence in a hidden field when a form has been submitted. For instance, when a form has been submitted, take the user's first character of their first name and first character of their last name, add a sequential number.
For example if Jane Smith submitted the 8th form entry, the hidden id would be JS-00008.
Hope this makes sense. Thank you for any help!
