How to count cells containing data and meet certain criteria
Can anyone help, I want to count the number of cells in 2 columns that match 2 sets of criteria. Basically I have a list of activities with dates next to them, like a record of work. I have on a separate page a table to summarise all the activities in rows and the months in columns. In separate columns I have managed to: - convert the full date to a numeric value ie; Jan = 1, Feb =2 - convert the "activity" to numeric value 1-20 I just need a formula to look down each column and count for each month how many times each activity occurs Is this possible? Please help....... :-) |

Yes, it is possible. You need to use an "array" formula. You will find it very handy. It takes a little getting used to, but once you've got it then you will find you use it all the time.
Where the functions countif and sumif will only work on one set of criteria, an array formula will let you work with multiple criteria - as many as you need. Cool! The following link has the best explanation that I've seen. http://www.cpearson.com/excel/array.htm Regards, Andrew [/url] |
