INDEX MIN function?

[MrRJ]

Hello,
I am thinking of using INDEX function, but not quite sure how to approach it.

Here is my sample data. I need to produce the last column with a formula.
Any ideas? If Column A is the same then what is the lowest value in Column C
then the answer is in Column B.
Results needed
9876 ABC Divison 145 Smart Move
9876 Smart Move 112 Smart Move
1234 Textile Co. 456 MMM Inc.
1234 MMM Inc. 78 MMM Inc.
1234 YAM 345 MMM Inc.
1234 Bee Corp. 154 MMM Inc.

This solution uses two extra columns to simplify the formulas. In D1 enter:

=MIN(IF($A$1:$A$100=A1,$C$1:$C$100,"")) and copy down
This is an array formula that must be entered with CNTRL-SHFT-ENTER rather
than just the ENTER key.

In E1 enter:

=MATCH(D1,$C$1:$C$100,FALSE) and copy down

In F1 enter:

=OFFSET($B$1,E1-1,0) and copy down
we now see:
9876 ABC Divison 145 112 2 Smart Move
9876 Smart Move 112 112 2 Smart Move
1234 TextileCo. 456 78 4 MMM Inc.
1234 MMM Inc. 78 78 4 MMM Inc.
1234 YAM 345 78 4 MMM Inc.
1234 Bee Corp. 154 78 4 MMM Inc.

The logic is:

column D get the minimum for each group
column E finds the minimum (row) for each group
column F retrieves the name

You can always combine formulas to remove the need for extra columns.

Your the MAN! Thanks a million!

Thank you for the feedback!

Hello,

Gary''s Student's solution does not show the correct result if
different classes have the same minimum or if a minimum of one class
appears at a lower row number for another class.

Enter 78 into cell C1, for example.

My suggested correction:
Array-enter into D1
=A1&"|"&MIN(IF($A$1:$A$100=A1,$C$1:$C$100,""))
and copy down.
Array-enter into E1
=MATCH(D1,$A$1:$A$100&"|"&$C$1:$C$100,0)
and copy down.
Enter normally into F1
=INDEX(B:B,E1)
and copy down.

The old solution in F1 would do but I would never use OFFSET if I can
use INDEX because OFFSET is volatile and INDEX is not.

Regards,
Bernd

PS: Use non-volatile INDEX(P11:IV65536,1+w,1+y):INDEX(P11:IV65536,w+y,x
+z)
instead of volatile OFFSET(P11,w,x,y,z).

Bernd P, you have too many helper columns.

Try this formula "No helper columns are required"

=INDEX($B$1:$B$6,MATCH(1,($C$1:$C$6=MIN(IF($A$1:$A$6=A1,$C$1:$C$6)))*($A$1:$A$6=A1),0))

ctrl+shift+enter, not just enter

Hello Teethless Mama,

You are right. Your solution is shorter and quicker (due to
FastExcel).

I just checked the first approach, found an error and focussed on
correcting it.
