Hiya I've attached a picture for reference. I'm currently at work and have been trying to figure this out for hours. So my task is to figure out which person made how many of each mistake. As you can see to right I can easily find out how many mistakes total were made by each person, but now I'm trying to see how many SPECIFIC errors were made by each individual (far right). So I've tried some SUM and COUNTIF formulae but I'm still pretty new to this. You can see in the bar at the top I managed to add together all the Incorrect nominal errors and all errors by Danielle but I want to find out how many nominal errors only Danielle made. Not a total of both. My 24 year old brain is about to explode.
Feel free to ignore columns E F and G as I've been playing around to see if that is the best way to do it.
