title: Validating two date-time local fields by earlier date?
body: <p>I'm currently having a problem. I have two date-time fields a Start Date and an End Date. If i pick a date on the Start date for example October 2,2016 and pick a date on the End date October 1,2016 an alert dialog box should appear that the end date is earlier than the Start Date. How do i validate this via script? Sorry i am still very new to programming.</p>
