Hi,

I'm trying to count the number of entries in a range B2:B1847 that are either
BKROCK
BLACKRCK
BLACKROCK
BLACROCK
BLK RCK
BLKRCK
BLKRK
BLKRO
BLKROCK
(note that these all have numerous strings of differing amounts of numbers on the end so I cannot use a RIGHT function)

The formula I had been using up until now was
=SUMPRODUCT((#other criteria#)*(LEFT(B2:B1847,2)="BL"))
but this returns BLACK RIVER which I don't want to count and doesn't include BKROCK OR BLKRO.

I also tried the following:
=SUMPRODUCT((#other criteria#)*(ISNUMBER(SEARCH("CK",B2:B1847))))
but this counts MAVERICK CAPITAL as well and not BLKRO.

I wondered if I could perhaps combine a SEARCH and OR function as follows
=SUMPRODUCT((#other criteria#)*(ISNUMBER(SEARCH(OR("BKROCK","BLACKRCK" ,"BLACKROCK","BLACROCK","BLK RCK","BLKRCK","BLKRK","BLKRO","BLKROCK"
),B2:B1847))))
but it just returns the value 0.


Does anyone know what I'm doing wrong and if there is another way around it?
Thanks!
