Query That Join Two Tables And Retrieve A Sum

I want to join two tables of information together. I want to bring the order information together with the order charge. But since the OrderCharges table can have multiple values, I just want to retrieve the sum of those charges for a specific OrderID+ItemID.

My data looks something like this:

CREATE TABLE #OrderItems
(
OrderItemsID INT IDENTITY (1,1) PRIMARY KEY,
OrderID INT,
ItemID INT
)
SET IDENTITY_INSERT #OrderItems ON

[Code] ....

So I'm looking to see a result set that would like this this:

OrderItemsID-----ItemID-----OrderID----OrderDescription--OrderCharge
----1------------124---------1------------Shipping----------6.55
----2------------156---------1------------Shipping---------16.85
----3------------156---------2------------Shipping----------7.40
----4------------158---------1------------Shipping----------7.85
----5------------158---------2------------Shipping---------15.25
