And Function with Array's

[CamB]

Hello All,

Quick Question, can an And statement be used with an array?

Excel Workbook
	A	B	C
1	List1	List2	Dupes
2	a	Hat	TRUE
3	a	Hat	FALSE
4	a	Chair	TRUE
5	a	Chair	TRUE
6	b	Phone	TRUE
7	b	Chart	TRUE
8	b	Charger	TRUE
9	b	Charger	FALSE
Sheet1

=IF(AND(A2 = "a", OFFSET(A2,0,2) = TRUE), OFFSET(A2,0,1),"")

will return the value of "Hat"

But if i feed it an array

=IF(AND(A2:A9 = "a", OFFSET(A2:A9,0,2) = TRUE), OFFSET(A2:A9,0,1),"")

A blank is returned.

Why is this?

Edit: yes i am pressing ctrl + shift + enter when computing the formula

The purpose is important. If you want to create an array (a vector), based on List1 = a and Dupes TRUE, then:

IF(A2:A9="a",IF(C2:C9,B2:B9,""),"")

This would yield something like:

{"Hat";"";"Chair";"Chair";"";"";"";""}

with the sample you posted...

I'm trying to build an array that looks at the cell next to it for a dependent list with no duplicates in the list for data validation. I'm trying to go 3 layers of dependent lists which have to be dynamic.

The values are returned correctly but when used for data validation it evaluates to an error.

I'm trying to build an array that looks at the cell next to it for a dependent list with no duplicates in the list for data validation. I'm trying to go 3 layers of dependent lists which have to be dynamic.

The values are returned correctly but when used for data validation it evaluates to an error.

If you want to create a filtered out list by means of formulas using a set of conditions such that it can be used in data validation, the best thing to do is to create such a list in an cell area and use that area as reference.

Consider...

E1: a

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

=IFERROR(INDEX($B$2:$B$9,MODE(IF($B$2:$B$9<>"",
    IF($A$2:$A$9=$E$1,IF($C$2:$C$9,
     IF(ISNA(MATCH($B$2:$B$9,E$2:E2,0)),
      MATCH($B$2:$B$9,$B$2:$B$9,0)*{1,1})))))),"")

The area under List can be referenced as the list to be used in data validation. Special care must be taken though. A dynamic named range cannot be processed using the Indirect function.
