# Excel - Average with #DIV/0!

Asked By TG Engel on 20-May-10 12:46 PM
```I am having a problem with an Average formula.  When I use a solution to a
similar question =AVERAGE(IF(ISNUMBER(B8:M8),B8:M8,FALSE)), it eliminates the

I have gotten around this by using:
IF(B8:M8=0,"",AVERAGE(IF(B8:M8<>0,B8:M8,"")))
BUT - if there is no value in cell B8 - the formula returns with nothing, if
there is a value in B8, the formula works as expected.  I find the very
bizarre.```

```Try this array formula** :

=AVERAGE(IF(ISNUMBER(B8:M8),IF(B8:M8<>0,B8:M8)))

** 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.

```=IF(COUNT(B8:M8),AVERAGE(IF(ISNUMBER(B8:M8),IF(B8:M8<>0,B8:M8))),"")

ctrl+shift+enter, not just enter```

```Another one:

=SUMIF(b8:m8,"<"&1E+199) / (COUNT(b8:m8)-COUNTIF(b8:m8,0))

1E+199
is a very large number in scientific format.

```Hi,

You may try this array formula (Ctrl+Shift+Enter)

=average(if((isnumber(B8:M8)*(B8:M8>0)),B8:M8))
