Use this code to limit the total number of entries that can be submitted for a particular form. This code will check if your entry limit has been reached and if it has, then the form will not be displayed.

Some actions may trigger more than once. A recurring payment can trigger an action after some time has passed. This example stops the form action if the entry was not created on the same day.

Use this code to get parameters from the URL to populate a checkbox field or multi-select dropdown.
