JavaScript code to add merge (combine) another document after the last page

Question

Hello there,I have an Expense Report, (it's one page), I would love to add a JavaScript code to a button to attach (add) the receipts after the Expense ReportSo once I click on a button I can browse the files I want and select one or all of them. I used these codes, but unfortunately, did not work var a = this.templates;
for (i = 0; i < a.length; i++)
    a[i].spawn(this.numPages, false, false);   var a = this.getTemplate("PageA");
a.spawn({nPage:this.numPages-1,bRename:false,bOverlay:false});    I tried to follow the links in this page, but they are not workinghttps://community.adobe.com/t5/acrobat-sdk-discussions/javascript-code-to-combine-pdf-files/td-p/9819122 Maybe I should to add a document level JavaScript codes? I hope it's an easy thing to doThanks in advance

"Inserting a page into a PDF is a major document modification, so it is not an operation that can be done in Adobe Reader, and it requires a Privileged Context. At its simplest, a Privileged Context means this operation cannot be done from a Document Level script, i.e., documents can’t insert pages into themselves. This has to be done from an Application Level script."

Is that mean the user of Adobe Reader can not insert pages, assuming I wrote the correct code?

Again, the only way to insert pages in Reader is through a Template. If you use any other methods, it will not work there. If you disable the button to insert pages via the Template object the end-users won't be able to insert any more pages.

Are the receipts PDF files or image files? If so, you can use a Template page with a single image field, spawn a copy of it and then prompt the user to select the receipt file as the icon of that field. They will need to do it one page at a time, though.
