    can i create a formula for an auto-fill field?

    Asked by jrobie23 on August 25, 2011 at 05:13 PM

    I'd like to "do the math" for my registrants.

    Basically if they put X as their birthday, I'd like to subtract that date from the current date and input their age.

    As I type that, I see that it is likely a bit much for a form!   :)

    Hi jrobie23,

    Thank you for using JotForm.

    Unfortunately, this feature is currently not available with JotForm. However, I will try to submit this to our feature request list and hopefully, our developers can implement this in the future. The best thing you can do for now is to obtain the form's full source code and add some programming codes/scripts.

    If you have further issues and concerns, please feel free to contact us again.
