"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Enter this in D2 and copy down

=IF(COUNTIF($A$1:A2,A2)=COUNTIF(A:A,A2),10%,"")

The formula below assumes you are looking
for a value of 500 in range A2:A8 and returns
10% of value if found, otherwise blank cell.

=IF(ISNUMBER(MATCH(500,$A$2:$A$8,0)),INDEX($A$2:$A$8,MATCH(500,$A$2:$A$8,0),1)*10%,"")
