Hi all

I can use =SUMIF(A1:A6,”=2″) to sum all 2 in a range.
Can SUM(IF….) do the same ? I can’t get the formula to work

cheers

It’s not clear what you want. Jerry has posted one possible solution. Depending on what you want to accomplish, you might use the following array formula (confirm with Ctrl+Shift+Enter) instead:

=SUM(IF(A1:A6=2,A1:A6))

You could use:

=COUNTIF(A1:A6,2)*2

SUMIF needs three arguements.
Perhaps =SUMIF(A1:A6, 2, A1:A6) will work for you.

(The =COUNTIF(A1:A6,2)*2 is possibly faster)

If the range to test the condition on and the range to sum are equal, you can omit the third argument of SUMIF – see SUMIF.

Thanks to all.

How does the =COUNTIF(A1:A6,2)*2 works?

The original formula

=SUMIF(A1:A6,”=2″)

adds the cells in the range A1:A6 whose value equals 2. If there is 1 such cell, the sum is 2, if there are 2 such cells, their sum is 2*2 = 4, if there are 3 such cells, their sum is 3*2 = 6 etc.
In other words, the sum is 2 times the number of cells that equal 2. COUNTIF calculates that number.

If you had wanted to sum the cells whose value equals 37, the sum would be 37 times the number of cells that equal 37, or

=COUNTIF(A1:A6,37)*37

1] COUNTIF can use in this way :

=SUM(COUNTIF(A1:A6,2)*{1,1})

2] Or, using SUMIF, and SUMPRODUCT function

=SUMIF(A1:A6,2)

=SUMPRODUCT((A1:A6=2)*A1:A6)

Please take a look of this :

SUMIF can accept the whole Column A, but SUMPRODUCT cannot.
