The easiest way is to change the formula tat computes the average to
something like =IF(D100,D10/C1,""). Then your AVERAGE formula will work
Alternatively, use the array formula
=AVERAGE(IF(ISNUMBER(B1:B12),B1:B12,""))
which must be entered with SHIFT+CTRl+ENTER not just ENTER

Hey there,
I'd like to get the average of a row filled with percentages. But because
the percentages will only be filled in when the month has started I have
some
div/0! values. How can I calculate the average? And please try to keep it
simple :D
Hope I explained it clearly, if not let me know, see an example below.
thx
Nagje
example (yes i know this isn't a row ;-) ):
Jan 95.2%
Feb 100.0%
March 93.2%
April 95.0%
may 96.9%
June 97.6%
July #div/0!
Aug #div/0!
Sept #div/0!
Okt #div/0!
Nov #div/0!
Dec #div/0!
Average year = ???????
