Hi

How does this formula really work?

=IF(ISERROR(INDEX('13DBC'!$A$1:$W$999,SUMPRODUCT(S
MALL(ROW('13DBC'!$10:$999)*('13DBC'!$C$10:$C$999< ""),ROW()-9+COUNTA('13DBC'!$C$10:$C$999)-COUNTIF('13DBC'!$C$10:$C$999,"0"))),COLUMN()-1)),"",INDEX('13DBC'!$A$1:$W$999,SUMPRODUCT(SMALL( ROW('1
3DBC'!$10:$999)*('13DBC'!$C$10:$C$999<""),ROW()-9+COUNTA('13DBC'!$C$10:$C$999)-COUNTIF('13DBC'!$C$10:$C$999,"0"))),COLUMN()-1))

I need to be able to manipulate the formula should I wish to reduce the
range from say 999 to 500.

I changing all the $999 to $500

and went to 13DBC worksheet, and deleted all the formulas from row 501
(this messed up the formula)

I see there is some kind of blue line that surrounds '13DBC'!
A09:S1001

It seems to be linked to make the INDEX formula work. I also tried
reducing that, and it messed up my formula's

What is the best procedure to reduce the range in the formula above and
in the area range in 13DBC?

Best to start by breaking it up.

First create a name, InsertNameDefine..., of say cCount, with a RefersTo
value of ='13DBC'!$C$10:$C$999.

Then create another name of say cSum with a RefersTo value of
=SUMPRODUCT(SMALL(ROW(cCount)*(cCount<""),ROW()-9+COUNTA(cCount)-COUNTIF(cC
ount,"0")))

then your formula becomes
=IF(ISERROR(INDEX('13DBC'!$A$1:$W$999,cSum,COLUMN( )-1)),"",INDEX('13DBC'!$A$
1:$W$999,cSum,COLUMN()-1))

You now have a much simpler formula that you can change the ranges here and
in the cCount name.
