Countif function

[ponygirl via OfficeKB.com]

I am trying to do an average of values in a range of cells across colunms,
where only values other than zero are counted in the divisor. For example, I
have 4000, 0, 0 in my range and I want it to average the sum by 1, and not by
3 since the other two values are zero. If I then add a value in the string,
as 4000, 2000, 0, my formula should then automatically average the sum by 2.
My formula is as follows:

=IF(ISERROR(+SUM(Z54:AD54)/(COUNTIF(Z54:AD54,"<>0"))),0,(+SUM(Z54:AD54)/
(COUNTIF(Z54:AD54,"<>0"))))

I have done this type of formula before using only positive values as in ">0"
and it has worked. However, this time I have both positive and negative
values and I want the formula to count all numbers other than zero in the
denominator. The problem is that even though I have specified not equal to
zero, i.e. "<>0", is still counts zero as a number and divides by 3 as in the
case of 4000, 0, 0. I have tried every variation that I can think of to solve
this problem: "<0<", ">0>", "<>"&"0", "<>"&B4 (where the value in cell B4 is
zero) and nothing works. Can someone help me out on this?

Try...

=IF(COUNT(Z54:AD54)-COUNTIF(Z54:AD54,0),SUM(Z54:AD54)/(COUNT(Z54:AD54)-CO
UNTIF(Z54:AD54,0)),0)

or

=IF(COUNT(Z54:AD54)-COUNTIF(Z54:AD54,0),AVERAGE(IF(Z54:AD54,Z54:AD54)),0)

....confirmed with CONTROL+SHIFT+ENTER, not just ENTER.

Hope this helps!

Does this *array* formula work for you:

=AVERAGE(IF(Z54:AD54<>0,Z54:AD54))
?
Array formulas are entered using CSE, <Ctrl> <Shift> <Enter>, instead of the
regular <Enter>, which will *automatically* enclose the formula in curly
brackets, which *cannot* be done manually.

Thanks! This works, except that I need to incorporate the ISERROR function
into the formula so that I don't get the #DIV0! error. Can you offer any
suggestions for that?

Works great! Thanks!

This will give you an empty ("") cell.
If you would prefer a zero, just replace the"" in the formula with a 0.

=IF(ISERR(AVERAGE(Z54:AD54)),"",AVERAGE(IF(Z54:AD54<>0,Z54:AD54)))
