Dynamically calculate Sum

[girapas]

In the column A of a sheet I put every month some employees names. In column B I put a number that indicates how much times each employee does a specific task.
I another column, say F, I have all the employees names, like that:
John
Tom
Mary
George
Steve
etc.
What I want is to get next to each employee name (say in column G) the total times (sum of numbers in column B) from the beginning (B1) so far.
Thanks in advance

Try

=SUMIF(A:A,F1,B:B)
