I have three ranges e.g.

Range 1 Range 2 Range 3
Bread Apples Bread
Apples Oranges Buns
Oranges Pears
Buns
Bread
Pears
Apples

I'm trying to construct a formula that counts the number of times, say, and
entry in Range 3 appears in Range 1 - In this instance the answer would be 3.
 
Hi,
try

=SUMPRODUCT(($A$2:$A$100=c2)+($A$2:$A$100=c3))

Being a2 to a100 range 1 and c2 and c3 products in range 3

Thanks, but is there a way to do this without enumerating everything in range
3. It's basically a lookup list that changes over time. I only want to change
the list, not everything that references it...
 
=SUMPRODUCT(COUNTIF(A1:A100,C1:C100))

Hi,

I assume your range to be counted is in column B

=SUMPRODUCT(COUNTIF(A1:A100,B1:B100))
 
Thanks, that's exactly what I need.

I'm not even going to pretend I know why that works when COUNTIF by itself
doesn't...
