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?
