Is there a list of formulas that work on closed workbooks?
After spending a fair bit of time trying to set up a spreadsheet that gets
data from another source and uses it I hit a wall when the COUNTIF() function
wouldn't work unless I opened the workbook.
I worked around it, and got a similar problem when I used SUMIF()

It's already harder than it should be due to INDIRECT() not working.

I just want to get some figures and totals from a vaste spreadsheet without
having to open the spreadsheet each time the criteria changes...
