How to find the maximum value from a column using another column as criteria in excel

Question

I have a dataset with person and values. I need to find the maximum value for each person. I wrote a function to find the maximum value for each person and gave 'ctrl+shift+Enter'.

=MAX(IF(A2:A34=A2,B2:B34))

When I drag this formula for all the person, the last few values for each person are not getting formulated correctly. Attached screenshot for reference. What is wrong that I am doing here?

Answer 1

Try it as,

=MAX(IF(A$2:A$34=A2, B$2:B$34))

... with CSE then drag down.
