When an interview is running, the interviewing program builds the pages that the browser displays by merging the question and response texts for the current question into the page template for the current page and combining them with other HTML code that is generated by the interview process itself.

If you want to customize these pages more than is possible by using page templates, you can do so by writing JavaScript, and editing the HTML page to include this code. Customizations of this type generally require you to refer to the form by name. The name of the interview page is mrFORM.
