Modify the existing formula

[wilchong via OfficeKB.com]

Dear sir,

There is 1 data set is assumed running in A1 down, viz.:
In A1 down is: 1,2,3,4,5,6,7,8,9, and 10
In F1 down is: 20, 7, 1, 12 and 8

And I have a excel forumula in the cell M1 as below:
{=IF(ROWS(M$1:M1)<=SUM(--(COUNTIF($F$1:$F$22,$A$1:$A$10)>0)),INDEX($A$1:$A$10,
SMALL(IF(COUNTIF($F$1:$F$22,$A$1:$A$10)>0,ROW($A$1:$A$10)-MIN(ROW($A$1:$A$10))
+1),ROWS(M$1:M1))),"")}

And then I drag the formula from M1 to M5. Therefore, the formula will give
me the result "1" in cell M1, "7" in cell M2 and "8" in cell M3. The formula
is extracted the value from F column according to the database in A column.
The formula also display the value from lowest value to highest value.

My question is that how can I modify the existing formula if I want to
display value in this order: 7,1 and 8. This order is exactly the order which
find in F column.

Many thanks,
Wilchong

Try this in M1, array-entered:
=IF(ROWS($1:1)>SUM(COUNTIF(A$1:A$10,F$1:F$5)),"",INDEX(F$1:F$5,SMALL(IF(COUNTIF(A$1:A$10,F$1:F$5),ROW(F$1:F$5)),ROWS($1:1))))
Copy down to M5.

Dear Max,

Many thanks for your advice and suggested formula, it works very well.
However, I found one thing which I don't really understand. The suggested
formula will give me the result as : 1, 12 & 0 after I moved the whole series
of data (20, 7, 1, 12 and 8) one cell downward (it means the series data
starting from F2). After I study the formular, I found that the result back
to 7, 1 & 8 after I revised the range in the formular ROWS starting from 1.
I don't understand why it will happen? Is that any way I can revise the
suggested formula even though I move the set data from F1 to F10?

Many thanks,
Wilchong

Try this in M1, array-entered:
=IF(ROWS($1:1)>SUM(COUNTIF(A$1:A$10,F$1:F$5)),"",INDEX(F$1:F$5,SMALL(IF(COUNTIF(A$1:A$10,F$1:F$5),ROW(F$1:F$5)),ROWS($1:1))))
Copy down to M5.

If you change this term:
ROW(F$1:F$5) in the earlier expression
to: ROW($1:$5)
that'll make it robust for your movement of the data series in F1:F5 to
wherever
