form fields need recalculation after pages are inserted or prior to viewing, printing

I have a two-page PDF (sample.pdf) that has a different form field (field01, field02) on each page that contains the formula:

event.value = "Page " + (event.target.page + 1) + " of " + this.numPages;

This lets each page calculate its own position within the document. This works fine until I insert a cover page. The revised document continues to show "Page 1 of 2" and "Page 2 of 2" until I bring up the console and manually call this.calculateNow(). Then the fields recalc and show "Page 2 of 3" and "Page 3 of 3" like I want. I want to change sample.pdf so that it recalculates after pages are added / deleted / moved or before it is viewed or printed. What event can I change so that sample.pdf is an easily insertable component of packets that I create?

TIA,

The easiest way to accomplish this is by creating a document level script that calls the recalculate function. When you create the script, make sure that you are calling that function outside of the function body that Acrobat suggests by default (you can delete that function, you don't need it).

You still would have to save and reload the document in order for the page numbers to be correct, but the next time somebody will open that document, the page numbers would be correct.

That makes sense. I've read about the Doc/Open event, but Acrobat 8 Pro will only guides me to creating scripts on Will Close, Will Save, Did Save, Will Print, and Did Print actions. If I name my own function in Document Javascripts and then follow the function definition with a call to the function, will that code run at Doc/Open?

That makes sense. I thought the document level scripts were just for definition of functions to be used elsewhere. I didn't realize that code can be called from them and it will run when the document is opened.

Thanks for your help.
