Can someone help me find the formula for cell K3, that can total instances of a given task based on the chart on the left? My names in each column aren't always the same so I can't simply have K3 sumif in column B. I'm trying to write a generic formula that I can copy and paste that I can use for other names. I'm thinking this may need to be a matrix formula, but it's been a while since I've used them.
