Hi Daniel

You can use an array formula: =SUM(IF(a1:a3=00001001,IF
(b1:b3=426351,d1:d4,0)))

Then press ctrl+shift+enter

my document is in column A:D.Column a is merchant id.
column b is bin number. column c is cr/dr and column d
is
the amount.

I want to write a formula to check if column a, b & c =
the true value that I want and if true, sums D:D.

Example:

column A column b column c column d
00001001 426351 cr 10.00
00001001 405262 cr 10.00
00001002 426351 dr 10.00

I want to write a formula that check if cloumn a =
00001001, b= 426351, c=cr, then sum d:d.
