I am using one of the fda forms(FDA 1572) found here **[Clinical Trial Forms | FDA](https://www.fda.gov/science-research/clinical-trials-and-human-subject-protection/clinical-trial-forms)**, which has a dynamic add-extra-page button, which should add extra pages. It works on adobe reader but does not work on pdfjs express webviewer. This is the error I get when I click the button :

Embedded JS error encountered, Mouse Up event on Field: ReferenceError: AddPage is not defined  
// VCK 5/26/13  
//  
// Continuation button for section 3 spawns T3-1.  
// Don’t add a page 3 if it has already been added.

Hi @vazearchis

Unfortunately PDFjs Express does not support page manipulation.

Thanks for your response! Is this a feature that is currently in the works? Or would we have to use adobe software to use page addition?

No page manipulation is not a feature we are working on. Please continue to use Adobe if that works with the FDA document.
