This can get a bit tricky with the security-related things that are in place now. It can be avoided several ways, one of which is to use HTTPS, a certified PDF form, and a properly configured crossdomain.xml file on the web server. This is discussed in a bit more detail here: http://www.adobe.com/devnet-docs/acrobatetk/tools/AppSec/enhanced.html
Thank you so much for getting back to me on this. I am going to check out the links you sent and get back to you on what I was able to figure out from them. In any case, I am sure that somewhere in the options you presented I will find the correct answer.
Good luck, and post again if you get stuck with anything.
