Hi Alwin,
Sorry to bother you, but the system still does not work correctly.
I use this system to request consent for the GPDR (RGPD in Spanish) of EU data protection
The system sent an email with the HASH key both to an email that I configured both to the person who fills the form and that email I control. That HASH key is the client's verification to the answer it has given us.
As you can see in the attached capture (I have deleted data by confidentiality, after here is your code, the hash key does not appear)
You can solve it or indicate how to solve it.?
Thank you very much for your work
