I am trying to calculate an average of numbers, based on who owns those
numbers. In summary, D4:D1000 will have a person's last name. M4:m1000 will
have a number entered into it. I want to average M4:M1000 but only using the
numbers that correspond with a single last name. For instance, the last name
Smith appears in d4:d100; I want to average only those numbers associated
with the Smith name. Also, I need to do this without sorting. My results are
on another sheet in the workbook so my information is contained in sheet 1,
but my formula (results) is located in sheet 2. Thanks in advance!
