=+COUNTIF(AC710:BG710,"*am*")+COUNTIF(AC710:BG710,"*pm*")+COUNTIF(AC710:BG710,"*audit*")-COUNTIF(AC710:BG710,"*redo*")-COUNTIF(AC710:BG710,"*pre-training*") when I use this formula, Excel won't accept it but does not say there is an error in it. If I change the ranges to search from AD : BG, then it works. Any idea why?
