    How to update field value on every change of another field

    Asked by mariusz.kaluska on March 03, 2015 at 04:01 PM


    I made a form in which I have a "phone number" field and a "control" hidden field. The value of this field is set to fill with "phone number" field when it is completed. However, when I change the value of phone number, control field no longer updates.
    Can I set the update control field each time someone change the phone number field, eg. At the exit from it field?

    1) Both fields are empty
    2) I enter the phone number 555 444 333
    3) Control field has a value of 555 444 333
    4) I'm going back to the phone number and change it to 555 444 555
    5) The control field still has a value of 555 444 333

    Can it be changed?

    Have you fixed the issue on form? When I test a cloned version of your form, it appears to be working properly.

    Thank You for Your help.

    The problem was, that I had comma in my conditions at the end of the arguments. Something like that

    If control field contains 555444333,555444222,555444111, then ..

    When I delete last comma everything works fine.

    Thanks one more.


    ps. Please, delete that gif with animation of my form.
