You are correct. I was wrong - and also entering the SUMIF function
incorrectly. Thank You!

No, sumif will NOT add the entire range, only those that has the 1 criteria
in A
although the array formula works it's a waste of resources compared to SUMIF
which is faster
and simpler

SUMIF will add the ENTIRE "B" column if there is ANY "1" in column "A". I
only want the values in column "B" added that match the "1" identifier in
column "A". I did remember how to do it. Use this array formula (enter
it
using Crtl-Shift-Enter after entering the formula into the cell you want
the
answer to be found): "{=SUM(IF(A1:A10="1",B1:B10))}" Do not type in the
curly brackets. Excel adds them when you enter the formula using the
Crtl-Shift-Enter combination to identify it as an array formula and not a
regular formula. If you just enter the formula using the Enter key, you
will
get an error. If there is another identifier, say "2", in column "A" and
you
want those values that match it in column "B" added, the array formula
looks
like this: {=SUM(IF(A1:A10="2",B1:B10))} - and so on.

Hi

no need for an array formula you can use the SUMIF function
=SUMIF(A1:A10,1,B1:B10)
or with the 1 in C1, in D1
=SUMIF($A$1:$A$10,C1,$B$1:$B$10)
this can then be filled down the other 'indicators'

I want to sum the values in column B using indicators in column A as
the
condition. For instance, all values in column B matching the "1"
indicator
in column A should be summed, and no others. Other indicators in
column A
are 2, 3, etc. I know this takes an array formula, but I don't
remember
how
to do it.
