These fields are: id 83, birth_month_day, and id 81, birthyear. Now, i'd like to use the gform_pre_submission hook to automatically show a birthday field that results in 83 plus 81. i.e. field id 85 shows mm/dd/yyyy. I am not a coder, but am making feeble attempts to do this. 2 of 3 forms have these age fields, the form ids are 7 and 11. Here is the gform_pre_submission example with my field ids. <pre><code><?php add_action("gform_pre_submission", "birthday"); function birthday(){ $_POST["input_85"] = "input_81"&"/"&"input_83"; } ?></code></pre> and—in the new birthday field, id 85, I have populate dynamically with the parameter, birthday. It is returning ) in the birthday field.
