Modify a Formula


C

Hello All.

I use this formula
=SUMPRODUCT(--(BOX!A5:A280=Sheet1!B12);--(BOX!I5:I280=TRUE))/COUNTIF(BOX!A5:A280;Sheet1!B12)

The range that it is looking at has values like #NUM! and the formula
returns #NUM!.

Is there a way to modify the formula so that it ignores the #NUM! ?

Thanks you in advance.

The range that it is looking at has values like #NUM!

Which range?

BOX!A5:A280
BOX!I5:I280
Sheet1!B12

Try this array formula** :

=SUM(IF(Box!A5:A280=Sheet1!B12,IF(ISLOGICAL(Box!I5:I280),IF(Box!I5:I280=TRUE,1))))/COUNTIF(Box!A5:A280,Sheet1!B12)

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT
key then hit ENTER.

Improvement...

We can shorten that a bit and save a few keystrokes:

=SUM(IF(Box!A5:A280=Sheet1!B12,IF(ISLOGICAL(Box!I5:I280),IF(Box!I5:I280,1))))/COUNTIF(Box!A5:A280,Sheet1!B12)

Still array entered!

Also, you might have to replace the commas with semi-colons as argument
separators depending on your international location.
