Array formula #/A

Why does IFERROR not handle blanks in # N / A in array formulas?

[AliGW]

Try this:

=IFNA(MMULT(A1:B2,A4:B5),"")

@Ali:
IFERROR actually works for all errors. IFNA is purely for NA errors. just like ISERROR and ISNA. besides, OP is using Excel 2010 if that is still valid in his profile. IFNA started in Excel 2013.

@chief_abound:
i'm not very familiar with MMULT, but why don't you upload a sample file for us to test?

Yes, I know that!

I had not looked at the OP's profile - my mistake on the Excel version.

IFNA() & IFERROR() doesn't work in this case
if you want "hide" #N/A use CF

Hi,

IFERROR doesn't work because the error is not returned by the formula itself, it is caused by entering an array formula into a range larger than the resultant array. You either need to correct the entry range or hide the errors using CF as sandy mentioned.

Hi! sandy666 Thank you

CF --> Does it mean conditional formatting?

[AliGW]

I don't see why you need the CF (conditional formatting). Just remove the formula from the cells where it isn't needed. You have a 2x2 array.

Hi! xlnitwit

Thank you so mych!

Thanks for your advice.

[chief_abound]

Hi AliGW

I just wondered what it means because I don't know what CF is.

I don't plan to use conditional formatting ... I will do what I can on your advice.

Thank you for your reply.

Hi! sandy666 Thank you

CF --> Does it mean conditional formatting?

Yes

here is example how it works

[AliGW]

Yes, which is why I put 'conditional formatting' in brackets so that you would know.

If that takes care of your original question, please select Thread Tools from the menu link above and mark this thread as SOLVED. Thanks.
