Sum A Union Select

Hi all

I'm new to SQL Server 2005 and its queries. I've created a DB that stores bonusses. For example, a person goes out with usually 4 other people, and does their work. The first person is the engineer, the second is the team leader, and the third and forth is the helpers. According to the number of notes they capture for that day, they get a bonus. if 3 notes has been done for the day, the enigeer gets 100 bucks per note, aka 300 bucks - 3 * 100 = 300. the team leader gets half of it, 150, and the helpers get each half of that, 75 and 75.

 in a select query i did the match/calculation

now i want to add everything up to get a total, 300+150+75+75 - how does one do it, and write it to a table? Note: The amount of people can change, the role of the person can change, so a helper can be a team leader or engineer as well, and the amount also changes depending on performance.DECLARE @BonusID int;
SET @BonusID = '1';


SELECT bd.BonusDetailID, bd.BonusID, u.Name, u.Surname, r.Role, b.Notes * a.Amount AS Total, bd.DateModified
FROM tblBonusDetails AS bd INNER JOIN
tblBonusses AS b ON bd.BonusID = b.BonusID INNER JOIN
tblUsers AS u ON bd.UserID = u.UserID INNER JOIN
tblAmounts AS a ON b.AmountID = a.AmountID INNER JOIN
tblRoles AS r ON bd.RoleID = r.RoleID
WHERE (bd.BonusID = @BonusID) AND (r.Role = 'Surveyor')

UNION

SELECT bd.BonusDetailID, bd.BonusID, u.Name, u.Surname, r.Role, (b.Notes * a.Amount)/2 AS Total, bd.DateModified
FROM tblBonusDetails AS bd INNER JOIN
tblBonusses AS b ON bd.BonusID = b.BonusID INNER JOIN
tblUsers AS u ON bd.UserID = u.UserID INNER JOIN
tblAmounts AS a ON b.AmountID = a.AmountID INNER JOIN
tblRoles AS r ON bd.RoleID = r.RoleID
WHERE (bd.BonusID = @BonusID) AND (r.Role = 'Team Leader')

UNION

SELECT bd.BonusDetailID, bd.BonusID, u.Name, u.Surname, r.Role, ((b.Notes * a.Amount)/2)/2 AS Total, bd.DateModified
FROM tblBonusDetails AS bd INNER JOIN
tblBonusses AS b ON bd.BonusID = b.BonusID INNER JOIN
tblUsers AS u ON bd.UserID = u.UserID INNER JOIN
tblAmounts AS a ON b.AmountID = a.AmountID INNER JOIN
tblRoles AS r ON bd.RoleID = r.RoleID
WHERE (bd.BonusID = @BonusID) AND (r.Role = 'Helper')

ORDER BY Total DESC
