Question

I have a form below:

"The Birth day" is less than "the Wedding day" and less than " Celebrates 1 year wedding day" and less than "Date of death".

I'm validate Birth day and Wedding day, then I realize the Wedding day must be validate with Celebrates day and Death day!!

The problem is : No field is Require! You can not check when the next field not fill?
If the Wedding not fill then you must be check Birth day with Celebrates day and if Celebrates day is
