I have a simple SQL Server cross tab select query. I'm trying to simply add a column at the far right named Total to add up the 7 column rows to the left but it keeps saying that its an invalid column name. I was trying to
Sum(A+B+C+D+E+F+G) AS Total

SELECT ProductsDetails.Gender, ProductsDetails.CorePN, ProductsDetails.productdescription, ProductsDetails.Color, ProductsDetails.Category, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 1 THEN Products.stockstatus ELSE 0 END) AS A, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 2 THEN Products.stockstatus ELSE 0 END) AS B, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 3 THEN Products.stockstatus ELSE 0 END) AS C, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 4 THEN Products.stockstatus ELSE 0 END) AS D, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 5 THEN Products.stockstatus ELSE 0 END) AS E, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 6 THEN Products.stockstatus ELSE 0 END) AS F, 
			SUM(CASE WHEN ProductsDetails.SizeNo = 7 THEN Products.stockstatus ELSE 0 END) AS G
FROM Products INNER JOIN ProductsDetails ON Products.productcode = ProductsDetails.productcode 
GROUP BY ProductsDetails.Site, ProductsDetails.Gender, ProductsDetails.CorePN, ProductsDetails.productdescription, ProductsDetails.Color, ProductsDetails.Category 
HAVING (ProductsDetails.Site LIKE N'Event Stock') 
ORDER BY ProductsDetails.Gender, ProductsDetails.CorePN, ProductsDetails.Category, ProductsDetails.Color

There are several ways of skinning this cat and it really depends on your version of SQL Server, if you are still using SQL Server 2000 you can do this:
SELECT  d.Gender,
	d.CorePN,
	d.productdescription,
	d.Color,
	d.Category,
	SUM(CASE WHEN d.SizeNo = 1 THEN p.stockstatus
		ELSE 0
	END) AS A,
	SUM(CASE WHEN d.SizeNo = 2 THEN p.stockstatus
		ELSE 0
	END) AS B,
	SUM(CASE WHEN d.SizeNo = 3 THEN p.stockstatus
		ELSE 0
	END) AS C,
	SUM(CASE WHEN d.SizeNo = 4 THEN p.stockstatus
		ELSE 0
	END) AS D,
	SUM(CASE WHEN d.SizeNo = 5 THEN p.stockstatus
		ELSE 0
	END) AS E,
	SUM(CASE WHEN d.SizeNo = 6 THEN p.stockstatus
		ELSE 0
	END) AS F,
	SUM(CASE WHEN d.SizeNo = 7 THEN p.stockstatus
		ELSE 0
	END) AS G,
	SUM(CASE WHEN d.SizeNo IN (1, 2, 3, 4, 5, 6, 7) THEN p.stockstatus
		ELSE 0
	END) AS Total
FROM    Products p
	INNER JOIN ProductsDetails d ON p.productcode = d.productcode
WHERE   d.[Site] LIKE N'Event Stock'
GROUP BY d.[Site],
	d.Gender,
	d.CorePN,
	d.productdescription,
	d.Color,
	d.Category
ORDER BY d.Gender,
	d.CorePN,
	d.Category,
	d.Color

Notice the way, that I am using aliases, this makes it easier to read.  Also, notice that I placed your condition in the WHERE clause instead of the HAVING.  Typically you use LIKE with wildcards so instead of say d.Site LIKE N'Event Stock', it could be d.Site LIKE N'Event Stock%'.  If you do want an exact match then I would write it as d.Site = N'Event Stock' and lose the d.Site in the GROUP BY clause

This can also be resolved with a derived table as follows:
SELECT Gender, CorePN, productdescription, Color, Category,
	A, B, C, D, E, F, G, A + B + C + D + E + F + G Total
FROM (SELECT	d.Gender,
		d.CorePN,
		d.productdescription,
		d.Color,
		d.Category,
		SUM(CASE WHEN d.SizeNo = 1 THEN p.stockstatus
			ELSE 0
		END) AS A,
		SUM(CASE WHEN d.SizeNo = 2 THEN p.stockstatus
			ELSE 0
		END) AS B,
		SUM(CASE WHEN d.SizeNo = 3 THEN p.stockstatus
			ELSE 0
		END) AS C,
		SUM(CASE WHEN d.SizeNo = 4 THEN p.stockstatus
			ELSE 0
		END) AS D,
		SUM(CASE WHEN d.SizeNo = 5 THEN p.stockstatus
			ELSE 0
		END) AS E,
		SUM(CASE WHEN d.SizeNo = 6 THEN p.stockstatus
			ELSE 0
		END) AS F,
		SUM(CASE WHEN d.SizeNo = 7 THEN p.stockstatus
			ELSE 0
		END) AS G,
		SUM(CASE WHEN d.SizeNo IN (1, 2, 3, 4, 5, 6, 7) THEN p.stockstatus
			ELSE 0
		END) AS Total
	FROM    Products p
		INNER JOIN ProductsDetails d ON p.productcode = d.productcode
	WHERE   d.[Site] LIKE N'Event Stock'
	GROUP BY d.[Site],
		d.Gender,
		d.CorePN,
		d.productdescription,
		d.Color,
		d.Category) a
ORDER BY
	Gender,
	CorePN,
	Category,
	Color

If you are using SQL Server 2005 and up then you can resort to using a CTE or a PIVOT.

Thanks a bunch Anthony, I usually do alias for the tables but figure I give a little more description. Thanks again for the extra info and other ways to go about this.
