Help with SUMIF
I am hoping to get some guidance on constructing a formula.
I am trying to calculate the number of days each person have been allocated for projects. This will help me in understanding monthly/annual labour allocation and available free time.
I have made column for each person on the right and entered the results I expect .
My logic for the calculation is - SUMIF(Primary Column = "John", get the value from Duration, and scan this through all the rows and add them)
I have attached a sample sheet.
Any help would be appreciated. Thank You
