Javascript to open multi-page doc to open to page two...?

We aim not to "provide" scripts, but more to help people learn how to make their own.

Now, I think I understand what you want to do but there's a big problem with it. If you want something to happen the FIRST time it's opened and not after that, it means you have somehow to REMEMBER that you've done it.

So... There are t places to remember, sorta. INSIDE the PDF and OUTSIDE the PDF. 

inside, implies you change the PDF and then SAVE IT. Because if it isn't saved, it isn't changed. This can work, but it relies on the end user accepting saving it. If they quit without saving, next time will be first again. Also,will they be reopening a saved file? If it's on a web site or in an email they will be opening a new copy each time, for the first time.

Outside seems attractive but Acrobat puts fearsome obstacles I the way of writing and reading files. There used to be global variables but I don't hear about them today, I think they were blocked.

My my guess is that you can't do this except in very special cases such as when you personally administer all the target computers.

You need to add a document level script to set the Acrobat JavaScript "pageNum" to the zero based value of "1".

// open PDF on page ;

this.pageNum = 1;

If you were to place this code on the Page 1 "Page Open" action you would never be able to access page 1 unless you added code to only run this statement once.
