I have a phone field and a hidden field called “Is Overseas number”. The hidden field value will not be saved and is only for form UI.
When a user enters a phone number in the phone field, a javascript validation function is triggered; the success or failure of this validation results in a string value being passed to the hidden field. Eg “Unknown” “Yes” “No”
I also have a radio button group called “Are you sure” with 2 options/choices; one YES and the other NO. There is no default selection or value.
In advanced options for the radio group I set “SHOW” when <hidden field name “Is Overseas number’> IS ‘YES’.
Unfortunately the “Are you sure” radio buttons never display AND I know the hidden field has the value of “YES”.
