Dear Experts,
this topic drives my crazy :-(
Date is a real challange in excel with all the different options and cases...

I have to check for several parameters including a date option which does not work as I expect it to work.

See attached file!

I want to find out how many people work in the Dept. JIM in Jan-12....later on I will import "fresh" data and I do not want to loose results for Jan-12 and on top get result for Feb and so on...

My idea:
As long an employee has "none" in the dismissal column it is clear that the person is working.
Like in the sample....up to Oct-11 we had 16 people working there.

With the help of my formula I did expect to have in my monthly updated table in the cell Oct-11 = 16 and the next cell Nov-11 would be 15 and of course in the cell jan-12 should be also 15....
what is wrong?
thanks for help
