I am trying to get a CountIFS formula to work that includes three sheet references and I get errors no matter what I do. I am trying to count the number of tasks with the isParent checkbox not checked, the Status equaling a specific value, and the Category also equaling a specific value. The values are represented in the cell references in the formulas I have most recently tried. What am I doing wrong? I don't care which one works, I just need something that works. Thank you in advance for your time and assistance.
