In previous versions of excel you could sum figures without a formula and see
the running tally in the bottom right of the screen. For example:

Column A Column B Column C
20 30 10
25 15 5
12 45 50

If I would select (aka highlight) 20, 15, 12; I would see a running tally of
47. But on my version of 2003 I no longer have that function.

Could someone please tell me how to get that function back? I hate to keep
creating formula for something so basic.
