hi,
I used a client's Gravity Form plugin copy and forum access to try to find a solution for a 30 days problem (for another client).
GF performed at first try, found an answer in the forums at second try.
Problem solved!
In the third move, I bought a developers licence.
Muchas gracias, Moltes gracies, Muito obrigado, Merci beaucoup, Danke Schoen, Grazia Mille, Arigato and Thanks a Bunch!
