Hoping the community can assist! 
These two COUNTIFS work separately.
=COUNTIFS({Finish}, >TODAY())
=COUNTIFS({PctComplete}, <1)
But why isn't it working when I nest them together? (it returns #Incorrect Argument Set?)
=COUNTIFS({Finish}, >TODAY({PctComplete}, <1))
If you care to, I'd appreciate answers to a few additional questions:
- I'm also confused with why the first forumla above requires the empty parens, but the 2nd formula is working without them.
- Smartsheet documentation shows square brackets [], but the actual software is inserting squigly brackets {}. Is there a difference?
Thanks,
Jon
