Calculating an average with conditions.
I have two columns of data, one of which I need to calculate an average of
but only if the data in the 2nd column is of a certain value. I can't work out how to do this... For instance, I need to calculate the average number of calls taken within week 37. My columns look similar to: No. of calls Week no. 10 37 8 38 4 37 etc |

Calculating an average with conditions.
This is an array formula that must be entered using ctrl+shift+enter at the
same time. =AVERAGE(IF(M1:M3=37,L1:L3)) -- Don Guillett Microsoft MVP Excel SalesAid Software "Rebekah" wrote in message ...

This is returning #DIV/0!
Is this because the "No. of calls" column is also subject to a formula?
