Question : Creating an automatic sum for specific cells - excel 2007

Dear Experts!

I have such table:

Column A     Column B
=================
Foo               12
Bar                40
Bar                62
Foo                20
Bob                10
Foo                 12

I would like to create some sort of a summit table, something like this:

Sums table
=========
Foo:   Total: 44
Bar: Total: 102
Bob: 10

My question is, how do I create a sum function automatically in such way, that the formula will know to sum all "foo" cells, and then "bar" cells and "bob" cells - So that I won't need to select the cell range myself?

Hope that someone understood my question :-)

Many thanks in advance!!!

Answer : Creating an automatic sum for specific cells - excel 2007

Use the SumIf formula...

=SUMIF(A1:A4,A6,B1:B4)

Where A1:A4 is the range of labels.. in this case your list of foos and bars etc
A6 is the foo or bar from sum table
and B1:B4 is the list of numbers to be summed.

Example Excel spreadsheet attached.
