Weighted Average with multiple Criteria

[EdE]

Hi,
I have a challenge of creating a weighted average with multiple criteria. I have data that is similar to this.

Region	Location	PN	Qty	Sales
USA	Dallas	1234	1	100
USA	Dallas	5678	100	10000
USA	NY	1234	100	10000
USA	LA	1234	10	100
USA	LA	1234	100	10000
USA	NY	5678	10	1000
UK	England	1234	2	200
UK	Ireland	5678	200	20000
UK	Ireland	1234	200	20000
UK	Ireland	1234	20	2000
UK	Scotland	1234	200	20000
UK	Scotland	5678	20	2000

<colgroup><col width="64" span="5" style="width:48pt"> </colgroup><tbody>
</tbody>

I need to find the weighted average of Sales based on quantity but where a certain combination of criteria is defined. I need the weighted Average of PN 1234 in the USA region in the LA location.
I know how to do this with one criteria but not multiple. Sumproduct formulas are not my strong suit.
thanks!!
