Hello,
I'm having trouble combining a couple functions in a COUNTIFS formula. Separately, they work fine, but combined they throw an INCORRECT ARGUEMENT SET error. The formula is:
COUNTIFS({GxP 7/8 Results}, NOT(ISBLANK(@cell)), {GxP Testers}, HAS(@cell, Tester@row))
I should say that {GxP Testers} references two adjacent multi-contact columns.
Any ideas on how to make this work?
