Hello,

I need a formula to sum Column C when the data across Columns E, F and
G haven't already appeared. In other words, if the data across Columns
E, F and G is listed more than once, Column C is counted once only.

C

100
300

200
400

If I understand you correctly, you want to sum column c on 3 separate
occasions - in column e, f and g. In each of these three columns you want to
sum column c only if data in the active column is not duplicated.

ie column e would sum only on the first instance of the character appearing
in that column. A, B, X and Y.

Rows 2 and 3 are the same, and rows 5 and 6 are the same. Therefore, we
are summing rows 1, 2, 4, 5 and 7. We are not summing duplicates.

hi!

assuming your data in A1:D7
use Advance Filer list range "A1:D7"
criteria range -leave blank-

check "Unique Records only"
check "copy to other location" range "of your wish"

the uniqe records will be copied down to a new location.
use "auto sum"
