I have a client that needs help and I know the sumif
function would work
here, but I must be doing something wrong. She has one
column with a letter
from A to G in it. In the other column is a number that
varies. She wants to
take, for example, all the cells with a B and add up the
numbers in the next
column for her total and do this for each letter.

D 12
D 6
D 30

D 18

E 12

E 24

Here are is a small portion of the sheet. Someone
suggested that I use this
command =SUMIF(R5:R256,1,M5:M256) where R5:R256 has the
letters and M5:M256
contain the values to add. I know this formula cannot be
write because how
does it know what letter to look for, but I don't know
how to fix it. Any
suggestions?
