Use the code below if you would like to stop a form action when one of two fields is empty. Replace 116 with your action ID. Replace 104 and 105 with your field IDs.

Only show your form before a specified date. This example closes the form on 2012-05-15.

Use this code to customize which date will be selected by default when a user pulls up the calendar. In this example, 20 years ago from today will be the selected date, if your calendar goes back that far.
