SQL calculation problem

Asked by Wytech_Wire in MS SQL Server, SQL Query Syntax, SQL Server 2005

Tags: Microsoft, SQL, 200 & 2005

I am trying to have this query calculate how much stock we have of a specific alloy, with the query below I should be getting a result of 81.57 but I am only getting 41.66. Somewhere it is dropping rows and I just cannot figure it out. When I structure these queries by themselves I get the correct calculation. It is only when I try to combind them that I get the lower result.

There are three tables involved:
tblAlloys = which hold the Alloy Name
tblInvTag = which hold the Stocks original values
tblInvXaction = which holds withdraws from the Inventory (Generally Negative numbers ex. -.91)Start Free Trial

SELECT DISTINCT tblInvTag.Diam AS Diams, SUM(DISTINCT tblInvTag.QtyOrig) + SUM(DISTINCT tblInvXaction.ActionQty) AS Leftover
FROM tblInvTag INNER JOIN
tblAlloys ON tblInvTag.AlloyID = tblAlloys.ID 
INNER JOIN
tblInvXaction ON tblInvTag.Tag# = tblInvXaction.InvTag
WHERE
(tblInvTag.Status = 'open') AND (tblInvTag.Diam BETWEEN '.02' AND '.02') AND (tblAlloys.DescShrt = '304V S/S')
GROUP BY tblInvTag.Diam
ORDER BY tblInvTag.Diam
