I have an array with 500+ elements. Assume elements 100, 200, 300, and 400
are equal to 'Sue'. For each occurrence of Sue, I want to find the row
number for the next occurrence and for the previous occurrence. At 100, I
get 200 and 'none'. At 200, I get 300 and 100. But when I get to 300, I get
400 and 100, altho I want 400 and 200. When I am at 300, is there some way
to have the search start at 299 and search backwards so that the first match
it comes to is at 200?

Assuming the names in column A, in a column on the right, say K, put this
formula

=IF(A1="Sue",COUNTIF(A$1:A1,"Sue"),"")

and copy it down. With the example you give, the formula should return 3 at
row 300. Then you can use

=MATCH(K300-1,$K$!:$K$500,0)

to get the row above and

=MATCH(K300+1,$K$!:$K$500,0)

to get the row below.

Of course, if "Sue" is just an example, and you really want to search for
other names as well, this isn't going to work.

Hi!

Not pretty but it works!

I assume there are no blanks in the array and you want
this for each element. My tests were based on a range of
A1:A15. Adjust to suit. In B1 I array entered this formula
with the key combo of CTRL,SHIFT,Enter:

=IF(ISERROR(SMALL(IF(A$1:A$15=A1,ROW(A$1:A$15)),CO UNTIF
(A$1:A1,A1)+1)),"none",SMALL(IF(A$1:A$15=A1,ROW
(A$1:A$15)),COUNTIF(A$1:A1,A1)+1))&","&IF(ISERROR( SMALL(IF
(A$1:A$15=A1,ROW(A$1:A$15)),COUNTIF(A$1:A1,A1)-
1)),"none",SMALL(IF(A$1:A$15=A1,ROW(A$1:A$15)),COU NTIF
(A$1:A1,A1)-1))

Copy down as needed. This returns the actual row numbers
and not the position in the array.
