Make sure one of the fields in a group of fields is required.

If your form is set up to allow editing, but you want to disallow editing when a certain field value is submitted, use the code below. Change 45 to the ID of your form, 123 to the ID of the field to check, and 'Closed' to the value that will prevent editing.

You can use the example below to remove the ID column and all of it's entry information from the .csv file of a particular form upon export.
