=IF(SUMPRODUCT(COUNTIF(A1:A7,A1:A7))=ROWS(A1:A7), "Yes","No")

Ooops! I think I have the Yes/No backwards. So, let's just change the
operator:

=IF(SUMPRODUCT(COUNTIF(A1:A7,A1:A7))ROWS(A1:A7)," Yes","No")

Yes = there are duplicates
No = there are no duplicates

Assuming there are no empty cells within in the range:

=IF(SUMPRODUCT(COUNTIF(A1:A7,A1:A7))=ROWS(A1:A7)," Yes","No")

How do I check whether the same string value appears within a range of
cells

e.g.

A
1 JD
2 DF
3 AM
4 FC
5 RS
6 DF
7 JD

How do I get excel to check down column A1:A7 to see if any of the
different
strings are repeated? In this example I want to return the answer "yes"
because JD appears in both A1 and A7. However, if this wasn't the case
then I
would want excel to return the answer "no"

I am using excel 2007

Many thanks

JD
