I'm trying to utilize the COUNTIFS function to see how often certain meeting rooms are being used throughout the day. I found an example online (noob, can't post link yet but it's from howtoexcelatexcel) that uses number of employees working, but I think I should be able to use it:
However, I can't get that example to work - the "Working Hours" on my sample always equals zero. I even tried making a copy of their example, and I'm still getting zeros. If someone could let me know what I'm getting wrong I'd appreciate it.
