Hi, there is no such hash variable #calcuSimple_approver#. You are probably looking for the User Hash Variable (Hash Variable#UserHashVariable)

Hi, what I am trying to do, is to get the user that is suppose to complet the approvement. Exemple: I want to approve something, and the approver is #calcuSimple_approver# which I mapped to the admin. I want to specified the email of #calcuSimple_approver# because, if I want to change the user mapped to #calcuSimple_approve# I also want the email tool to change automaticly. Thank you

I don't understand why this is working then. See the other reponse please. My email is recognize when I call the applicant, but isn't when I call the approver. I don't understrand. Thank you

Instead of setting the specific email address, you can try just setting the To (Participant ID) to the participant ie calcuSimple_approver. That should send the email to the user mapped to that participant.
