How do I extract pages from a current open pdf via script?

Question

I am using the following script to extract all pages to seperate pdf files, but nothing happens??
var filename = "PageOutput";
for (var i = 0; i < this.numPages; i++)
    this.extractPages({
        nStart : i,
        cPath : filename + i + ".pdf"});
Any ideas.  This code was taken directly from the Acrobat javascripting Guide.  The guide is for version 7, I am using version 9.

You do not need to use a menu item. You need a script that is at the application folder level, in a batch process, or an added menu item. Adding a menu item requires and application folder level script or console JavaScript.
To save a file see How to save a PDF with Acrobat JavaScript by Thom Parker.
To add a custom menu item see Adding Custom Menu Commands by Ted Padova or Add a Custom Menu Item to Acrobat by Thom Parker.
You should also download the Acrobat JS API Reference from the Adobe Acrobat Developer Network.
