I have a view I am trying to add a column to. The new column will be computed by taking 3 other columns. Essentially I want a sum of (ColA -(ColB+ColC)) . In my ALTER View statement I am trying to create a column  by using the statement below. Any idea as to how to do this.  I should mention i want totals to be per row and not a grand total. Any help would be greatly appreciated.
ALTER VIEW [dbo].[v_viewinvoicetot]
AS
SELECT SUM(orderTbl.totprod_nm - (orderTbl.sandh_nm + orderTbl.tax_d)) AS totprodnm_custom
 
FROM         invoiceTbl INNER JOIN
                      orderTbl ON invoiceTbl.orderid_i = orderTbl.orderid_i
