ACtual Carol, I just came across that bit of text a few minutes ago also! But here's the problem, I remembered that I filled a form once that I was able to save the fields inside, so I opened that document, and I found that in the "Document Properties" Security settings, everything listed said "Allowed", and for this form that I am having trouble with, 3 of the options in the list say "Not Allowed" including the one that says Changing the document (is not allowed).
SO, I need a way to change the Document Restrictions so that everything says Allowed. I tried making the pdf again from scratch using Adobe Designer, but the same thing happens and I can't find where to change these settings, called "Document Restrictions", and furthermore, the phrase "Document Restrictions" doesn't appear in the help dialog. That's another pet peeve of mine, when a help file doesn't contain the exact phrase that they use to define something in the program.
