IF Formula to go through every line of array

[Leibtek]

Hi,

I have a worksheet with items numbered 1 through 5000, I have another worksheet with the item categories. The categorie's worksheet has two columns that indicate the range of items belonging to that category (i.e. Column A = "Casual", Column D = 23 - Column E = 40 [Casual belongs to items numbered 23-40]).

How do I get the category name in the item worksheet in its corresponding items?

I've tried vlookup, if..etc. looks like I need a combination of both.. If somone can please help..

Thanks,
Leibtek

Hi!

> (i.e. "Casual", Column D = 23 - Column E = 40

Assuming this is the layout:

......C...................D...............E
Casual................23..............40
Formal...............41..............58
Liesure...............59..............76

>items numbered 1 through 5000

Are in the range A1:An

Enter this formula in B1 as an array using the key combo of
CTRL,SHIFT,ENTER:

=INDEX(C$1:C$3,MATCH(1,(A1>=D$1:D$3)*(A1<=E$1:E$3),0))

Copy down as needed.

Add your sheet names and adjust the ranges to suit.

Thanks Biff...

=INDEX('Sub Category'!C$2:'Sub Category'!C$171,MATCH(1,(B2>='Sub Category'!M$2:'Sub Category'!M$171)*(B2<='Sub Category'!N$2:'Sub Category'!N$171),0))


I'm getting the #N/A error

When I evaluate the formula, the MATCH argument returns "true*true" then returns the #N/A.



Thanks,

Hi!

Array formulas are different.

Normally when you type a formula like: =SUM(A1:A10), you hit the ENTER key
to place the formula in a cell.

With array formulas there is a special sequence of keys that you MUST use.
Type the formula then hold down both the CTRL key and the SHIFT key then hit
ENTER. When done properly you'll see in the formula bar that the formula is
enclosed in squiggly braces { }. The braces denote an array formula. You
MUST use the key combination, you can't just type in the braces. Also, if
you edit an array formula it MUST be re-enteed as an array.

> Also, when you say "Match(1," what are referring to with the "1"?

When these arrays are multiplied together:

(A1>=D$1:D$3)*(A1<=E$1:E$3)

they will return either a 1 if the condtion(s) is true or a 0 if the
condition(s) is false. It would look something like this:

MATCH(1,{0;1;0}

Match 1 matches the 1 that's in the second position. This matching position
(2) is then passed to the Index function and the result of the formula is
the second value that is indexed in the Index function:

=INDEX(A1:A10

The value that would be returned is the value in A2 since it's in the second
position.
