SUM function for DISTINCT rows

[Guest]

Hello-

I have a table like this

tbl_WorkDetails
WorkDate
WorkProject
WorkHours

....with values like this:
WorkDate WorkProject WorkHours
06/01/2005 ProjectA 4
06/01/2005 ProjectC 2
06/02/2005 ProjectA 2
06/02/2005 ProjectB 2
06/02/2005 ProjectC 4
06/03/2005 ProjectA 4
06/03/2005 ProjectC 2
06/04/2005 ProjectA 2
06/04/2005 ProjectB 2
06/04/2005 ProjectC 4

What i'd like my report(query) to show is this:
WorkProject SumOfWorkHours
ProjectA 12
ProjectB 4
ProjectC 12

I imagine a query like this:

SELECT DISTINCT WorkProject
FROM tbl_WorkDetails
ORDER BY WorkProject;

....and then one like this (coding help provided by Marshall Barton):

SELECT T.WorkProject,
Y.DistinctWorkProjectQuery,
Sum(T.WorkHours) AS SumOfWorkHours
FROM tbl_WorkDetails As T INNER JOIN
[SELECT X.WorkHours
FROM DistinctWorkProjectQuery As X
GROUP BY X.WorkHours]. Y
ON Y.WorkHours= T.WorkHours
GROUP BY T.WorkHours, Y.DistinctWorkProjectQuery

so

the code runs just fine, but the math is bad bad bad. Any thoughts on why
this is?

Thanks!

Amelia,

How about like this?...
SELECT WorkProject, Sum([WorkHours])
FROM tbl_WorkDetails
GROUP BY WorkProject
