protect document

How do I protect a document, so that when I email somebody an invoice for
example, they cannot change any of the information on it?

Also, I have a column of numbers. Now what i'd like is to work out the
average of these numbers. Is it simply =AVERAGE(A1:A30) for example?

Neil, on the invoice, get a PDF print driver (~$25) and then just create a
PDF file. Most PDF print drivers will let you make the PDF password
protected. I use the one from www.docu-track.com

And yes to your question on average.

Hi
though you can use 'Tools - Protection' this kind of security is quite
weak. There's no secure way to protect your Excel files.

For your second question: Yes that simple :)
