I am not trying to multiply column M and column S. I am trying to add all
the numbers in column S that correspond with text in column M that begins
with the letter "A"

I have a datatable with a number of columns and I want to add all the
numbers
in column "S" when the text in column "M begin with an "A". I also
want
to
use the same function for all the numbers in Cloumns "T", "U", "V",
etc.
I have tried =SUMIF($M$3:$M$100,LEFT($M3,1)="A",S3:S100) and all I get
is
"0". Any suggestions?
