[dynamichidden user-email "CF7_get_current_user"] will return the username, but if I add any other value, like:
[dynamichidden user-email "CF7_get_current_user key='user_ID'"]
it doesn't return anything. This is the case for when I try to use email, or any other field I tried. It looks from these forums that other people are having success with this, so I wonder what I'm doing wrong. Please let me know, thanks.
