Index with small limitations

[mbarbera83]

Hi all.
I am trying to create a list of products by brand, using the Index function with Small, but it seems that my data base is too big for the memory. when i index only to row 21, then it works, but when i take it to row 1500 which I need, i get an error

=IF(ROWS(E$3:E3)>E$2,"",INDEX($A$2:$A$21,SMALL(IF($B$2:$B$21=E$1,ROW($B$2:$B$21)-ROW($B$2)+1),ROWS(E$3:E3))))

is there any way to get around this?

<tbody>
</tbody>

Product	Brand			Brand1	Brand2
product1	Brand1			=count Brand1 in column B	=count Brand2 in column
product2	Brand2			FUNCTION GOES HERE
product3	Brand1

<tbody>
</tbody>

Why don't you use filter or advance filter
those are two great tools

Row\Col	A​	B​	C​	D​	E​	F​
1​	Product	Brand			Brand1	Brand2
2​	product1	Brand1			2​	1​
3​	product2	Brand2			product1	product2
4​	product3	Brand1			product3
5​

E2, just enter and copy across:

=COUNTIF($B$2:$B$4,E$1)

E3, control+shift+enter, not just enter, copy acsoss, and down:

=IF(ROWS(E$3:E3)<=E$2,INDEX($A$2:$A$4,SMALL(IF($B$2:$B$4=E$1,
   ROW($B$2:$B$4)-ROW($B$2)+1),ROWS(E$3:E3))),"")

I need this to be dynamic, as the product list changes, and i am using the final result to create validation lists.

You skip post #3...

I am aware of the Array cntrl shift enter function, the problem is that as soon as the data in column A goes over 22 lines, (my data is 1400 lines long) the array does not work

Really? Why don't you check it out the suggested set up?

No.

See the workbook that implements the formula set up: https://dl.dropboxusercontent.com/u/65698317/mbarbera83 brand sublists.xlsx

apologies - i did not realize that there was a change in the formula. but even with your formula - as soon as i extend the array further down the column, then i get #VALUE
