Hello!
I found a similar topic but I opened another one because I didn't really understand how to do this.
OK... so I have a spreadsheet with all these different dates and instead of having to create a column every time I want to subtract one from the other, I'd rather have the function do that for me (which it does). The problem is that it shows as invalid.
So for example I have
PO Create Date STA Date
3/18/2014 5/27/2014
3/18/2014 5/27/2014
3/18/2014 6/24/2014
I want my average if to subtract the 2 values instead of having to create a column to do that for me.
I hope you guys understand what I'm trying to do here!
