Making buttons to add and REMOVE optional pages of a form

[Christopher Teacher]

I am creating a form that has some pages which are optional based on user's needs.  I've figured out how to place buttons that will spawn those additional pages based on embedded templates; however, I also want to have buttons that will hide said pages again in case someone adds one in error.  The script I used in the buttons to add the pages is this:

var a = this.getTemplate ("Interview notes");
a.spawn();

I tried using this script in a "Remove Page" button... 

var currentPageNumber = this.pageNum;

this.deletePages({nStart: currentPageNumber, nEnd: currentPageNumber});

...but unfortunately it deletes the whole page template meaning that the add page button no longer does anything within that version of the file.  

I also tried the following:

Add page- 

var t = this.getTemplate ("Interview notes");

t.hidden=false

And this for the remove page button:

var t = this.getTemplate("Interview notes");

t.hidden=true  

This worked beautifully... until I opened the file in Acrobat Reader rather than Pro, and then it didn't work at all (all template pages were visible all the time).  

Basically, I need something that does the opposite of the "spawn" command, and gets that template back to a hidden state without removing it entirely.  

Thank you!

As you've seen. A field script in Reader can delete, but not hide a template page. So the correct method for using a page template is to always hide the template up front (at design time). If a template page is needed in the initial document, then it should also be spawned up front. Then a script can be used to delete it. 

Again, the correct method for using a page template is to spawn and delete pages from the original template, which is hidden.

So, no way to re-hide it after it has spawned?

No, Template pages are spawned and deleted. Never hidden. The hidden attribute for the template is a convience for form design. It is not used at runtime.
