VLOOKUP() style but 3 value lookup

Hi all,

I have a table that has, amongst many columns, a year, month and a name column.

I want to do a formula that takes in 3 values (name, year, month) and returns a sum of values found in a variety of other columnswhere these 3 values are matched.

I would know how to do this in SQL but wonder if Excel can do this type of thing on one large data table?

Cheers
David
