Hi there!

I inserted a date, for example (Nov-08) in the cell H1 of an excel
sheet. I have used the date format and date function.
Now, I'd like the software to automatically fill out the adjacent cell
(s) [G1] with the previous month(s), e.g.: Oct-08.

I got surprised to see that writing "=H1-1" in cell G1 doesn't make it
happen; it just copies "Nov-08".
Can you give me a help?

Thank you in advance for your support!

best,
alf
