return a zero for error
Hi Jerry,
I tried your solution and it worked, but it's new for me that COUNT(B5:B20)
used as a criterium returns a Boolean value required by the IF function as
first argument, while using as a separate function returns an integer. It
seems that if COUNT(B5:B20) returns zero then its logical value is FALSE, it
it returns a positive integer then its logical value is TRUE. Is it so? How
do you find out such tricks, Help doesn't mention this possibility?
Regards,
Srefi

If in the workbook this will be repeated many times or involve a much
larger range, then it might recalculate faster to cut out the math
=IF(COUNT(B5:B20),AVERAGE(B5:B20),0)

I'm having a problem with a spreadsheet I'm developing which records average
marks of groups of students over several weeks. I want to display a
"Running Average" of those averages as I enter the data, however, because I
do this week by week there are inevitably weeks which have not had any data
entered and her I see the error #DIV/0! for the formula
=AVERAGE(IF(R5:R20<0, R5:R20,"")). I do understand why I'm getting this
(because I'm dividing by zero) but would like to return a zero so that the
average of the averages will return a number rather than an error.
Can anybody help me?
Pete
