COUNTIFS with ranges
Hi,
I have a task list with a flag column and collaborators in 5 columns, so a collaborator could be the primary responsible or up to a 5th level involved in a task. I haven't been able to use Countifs function in a formula which will retrieve from the list how many tasks a given worker is involved into, the function works well up to one column, but when I expand to 2 contiguous columns it will generate an error.
At Risk TaskName Assigned To 1_2 Assigned To 2_2
Y Task 1 Worker1 Worker2
Y Task 2 Worker3 Worker1
N Task 3 Worker4
This returns 1:
=COUNTIFS([At Risk]:[At Risk], true, ([Assigned To 1_5]:[Assigned To 1_5]), "Worker1")
While this returns "#Incorrect argument set", I'd expect a value of 2
=COUNTIFS([At Risk]:[At Risk], true, ([Assigned To 1_5]:[Assigned To 2_5]), "Worker1")
Any thoughts?
Thanks

Your first error is that you need to use "Y" as your criterion for At Risk:At Risk.
=COUNTIFS([At Risk]:[At Risk], "Y", ([Assigned To 1_5]:[Assigned To 1_5]), "Worker1")
See if that produces the correct answer of 2. Then troubleshoot to see if your multiple column range will work as well. From first glance, it seems like it should.

Multiple columns don't work in COUNTIF(S) or SUMIF(S). You would have to count each column separately and add them together.
=COUNTIFS([At Risk]:[At Risk], "Y", ([Assigned To 1_5]:[Assigned To 1_5]), "Worker1") + COUNTIFS([At Risk]:[At Risk], "Y", ([Assigned To 2_5]:[Assigned To 2_5]), "Worker1") + COUNTIFS([At Risk]:[At Risk], "Y", ([Assigned To 3_5]:[Assigned To 3_5]), "Worker1") + etc...

That's what i was thinking as well, Paul. Adding those Countifs together would do the trick.
