Countifs Function with Multiple Criteria - Best Practices?
Hello! I'm having trouble understanding the best way to count multiple criteria in a countifs function. I can write simple countifs formulas, but the more criterion and ranges I add (seeking "and/or" results), the more errors I get. I struggle with combining ranges and criteria, I think because I don't understand how best to write or maintain a proper syntax as the formula becomes more complex.
In the examples attached, I get a nested criteria error or an incorrect result when I try to add two formulas. What am I missing? And how can I get better at this? :)
