I found a script that I thought would work great for password protection of some low-level (not critical at all) powerpoint slides.
Here is the URL: http://javascript.internet.com/passwords/cookie.html

The problem is that I don't understand how to set the password in this script and I'd rather use one password instead of three. Can someone help me with that?

Thank you!
