Hi Dave

If you have XL2003 then use DataLists
This will automatically extend your list for you including any formulae
as you add more rows at the end.
This feature is even further enhanced (and better) in XL2007.

Bernie,

The formula I have in column N is (in row 4 for example) =SUM(K4-E4)
where columns K & E contain dates, hence column N displays the length
of stay in days. The check box you mention was already ticked so it
seems as if I'd already achieved what I wanted but just didn't know
it.

Thanks to you and Bob. :)

Dave,

You need to be a little more specific - do you want a formula in each
cell of a column where the
other cells are filled in, or just a formula that is based on any cell
in a column.

If the first, use the option of extending lists: Tools / Options..
Edit tab, check the box next
to "Extend List formats and formulas"

IF the second, write your formula like

=SUM(A:A)

instead of

=SUM(A2:A100)

I want to set a simple (k-e) formula to apply to all rows in a
column rather than to a finite set
of rows. This is because I want people to be able to add an
indefinite number of rows without the
formula suddenly stopping working. Is this possible? (I asked my
work IT helpdesk but they didn't
know how to do it nor whether it was possible! :)

thanks folks,
