Filtering Data w/ Query
I know query is exactly the tool I need to use, I just have no idea how to use it!

I have the following query function:

=query(B29:D;"select B,sum(D) where B <> '' group by B label sum(D) '' ")

and it works fine, except now, I need to filter the data in column B based on what is in column A, before the query works its magic. I'd typically just use Filter, I'm thinking that ALL of this can probably be done with query, I just have no idea how.

https://docs.google.com/spreadsheet/ccc?key=0AkRGrGvH7D6edHNyTlVNTnNLZ3NHWnhIU0s4WDk2dEE#gid=92

You can see the query function in C6, and it's adding up all the hours in rows 29 and below, except I want to filter those hours based on the date in column A. And there is a drop down menu in C2 that I choose which date I'm looking at.

Does anyone have any ideas?

Thanks!
