SQL-Server-2008R2

I have 3 table imported from msaccess to sql server
0.Sumo_Stocks
1.Sumo_In
2.Sumo_Out
i want to create a query to sum all qty from [Sumo_In] and [Sumo_Out] and compute all actual qty.

What I have tried:

SELECT Sumo_Stocks.ID, Sumo_Stocks.Description, Sumo_Stocks.Unit, 
(SELECT SUM(QTY) AS [IN QTY] FROM  Sumo_In WHERE Material_ID=Sumo_Stocks.ID) AS [In Qty], 
(SELECT SUM(QTY) AS [OUT QTY] FROM  Sumo_Out WHERE Material_ID=Sumo_Stocks.ID) AS [Out Qty], 
IIf(IsNull(IIf(IsNull([In Qty]),0-[Out Qty],[In Qty]-[Out Qty])),0,IIf(IsNull([In Qty]),0-[Out Qty],[In Qty]-[Out Qty])) AS [Actual Qty]
FROM Sumo_Stocks

This code is work fine with msAccess but when i tried to SQL Server, Error Msg 174 appear.

Here is IIF statement to get actual/current Qty.

IIf(IsNull(IIf(IsNull([In Qty]),0-[Out Qty],[In Qty]-[Out Qty])),0,IIf(IsNull([In Qty]),0-[Out Qty],[In Qty]-[Out Qty])) AS [Actual Qty]

I solved my problem.
Here is my code now.

SQL

SELECT Sumo_Stocks.ID, Sumo_Stocks.Description, Sumo_Stocks.Unit, 
(ISNULL((SELECT SUM(QTY) AS [IN QTY] FROM  Sumo_In WHERE Material_ID=Sumo_Stocks.ID),0)) AS [In Qty], 
(ISNULL((SELECT SUM(QTY) AS [OUT QTY] FROM  Sumo_Out WHERE Material_ID=Sumo_Stocks.ID),0)) AS [Out Qty],
(ISNULL((SELECT SUM(QTY) AS [IN QTY] FROM  Sumo_In WHERE Material_ID=Sumo_Stocks.ID),0))-(ISNULL((SELECT SUM(QTY) AS [OUT QTY] FROM  Sumo_Out WHERE Material_ID=Sumo_Stocks.ID),0))
AS [Actual Qty]
FROM Sumo_Stocks
