Hi
I have two columns of data one with numbers (columnA) and the other with Y or N (column b)
What I'd like to do is find the last instance of a number in column A and return the corresponding B value. Column A value can appear any number of times.

e.g

Column A Column B
100 N
101 N
101 Y
102 N
103 N
103 N
103 Y
104 N
104 Y

Essentially for each of 100,101,102 etc I want to look at the last instance of it in column A and return to my secified cell what the corresponding B value is

All help appreciated.

Thanks
Will.

for 100 try:
=INDEX($B$1:$B$100,LOOKUP(2,1/($A$1:$A$100=100),ROW($1:$100)))
you also can change the value with a cell reference

Hi Claus,

That appears to do the job nicely, thank you, will try it on a larger data set later on..

Thanks again
