Hey All,

I have a problem with a code i am trying to use. This code,
SUMPRODUCT(--(ISNUMBER(FIND(C2,$A$2:$A$200,1))),--($B$2:$B$200=B2+5)),
does not help me in solving a problem i am trying to solve. This is the
problem. I have in A1:A100 twenty 6-digit numbers, and in B1:B200 is the
years. I am trying to find if my value in C1 matches the values in
A1:A100 range and the B1:B200 range. Let me give an example. C1=123456
and B1=1985. Now can you help me find a way to find the number of times
C1 occurs in the A1:A200 range and at the same time match only the Years
1985,1986, 1987,1988 and 1989 in B1:B200. *Remember the years 1988 and
1989 may not be in the range B1:B200.* I need to find an efficient way
to calculate for C1,C2,C3 and so on. Please help

Hi,
Referring to your previous postings and replies:

What is the relationship between contents of A1:A100 and B1:B200?

If we find 123456 occurs 100 times in A1:a100 how does this relate to a year
e.g 1985? How do they "match"?

Here are a list of numbers, where the 1st row is C cell values and the
second row years is B cell Values. So can you help me find an efficient
way of counting 4735578 where it should look within the last 5 years
from 2001 and at the same time count the number of times it occurs in
A1:A200. The constraint is the some years are not there in the C1:C200
range.

I see you had two replies yesterday (from people more expert than myself) ,
both of which indicate to me the difficulty we are having; not least because
the values in B in your example are 7 digits whereas in your original post
you said the cells in A contained 6 digit numbers!

So my attempt assumes the following:

EACH cell in A1:A200 contains 20 numbers of 6/7 digits separated by a blank.
I look for maches in the whole range for a given B value i.e. match B1
against ALL A1:A200 (4000 numbers (200 *20) and then check the C range to see
if it matches a year.

Again, this only makes sense if the same B value occurs for more than one
year; your sample data doesn't show this.

In the example below, it finds values where year is <=2001

If there are still problems, mail me a workbook with an actual example and
result to

=SUMPRODUCT(--(LEN($A$1:$A$200)-LEN(SUBSTITUTE($A$1:$A$200,$B1,"")))/LEN($B1),--($C$1:$C$200=2001))

Put this in D1 and copy down.
