    Logic Question

    Asked by chabad on February 16, 2014 at 03:12 PM



    I have a calendar of dates that I want users to pick from. But the program they are signing up to is a one week program. So I really want them to just pick the start dates and let the registration calculate seven days later as thier end date. Is this possible?

    Yes this is possible in JotForm.

    You can use the Date field in condition logic to compute another date by using +number or -number  (number is the days i.e. +7 in your case)

    The calculation field feature can also compute days between 2 dates.

    Here is a sample form that shows this http://www.jotform.me/form/40465810537454

    For more complex programmable calcutions, you will need to use the form's source code and then create your own calculation code function.
