Nee help - How To get AVG in his situation?

Hi All,
Below is my initial query, that returns totals for each w within the
month specified. I hard coded the W Columns to make it easier to work
with. This works fine.
/*---*/
Select T1.DataSource AS [Service Line],
COUNT(T1.PoNumber) AS [Total Of PONumber],
Sum(Case When T1.ReqSubmitDate
Between '04/01/2005' AND '04/2/2005' Then 1 End) [04/2/2005],
Sum(Case When T1.ReqSubmitDate
Between '04/03/2005' AND '04/9/2005' Then 1 End) [04/9/2005],
Sum(Case When T1.ReqSubmitDate
Between '04/10/2005' AND '04/16/2005' Then 1 End) [04/16/2005],
Sum(Case When T1.ReqSubmitDate
Between '04/17/2005' AND '04/23/2005' Then 1 End) [04/23/2005],
Sum(Case When T1.ReqSubmitDate
Between '04/24/2005' AND '04/30/2005' Then 1 End) [04/30/2005]
FROM OPW AS T1,
(SELECT PoNumber
FROM OPW
GROUP BY PoNumber
HAVING COUNT(*)>1) AS T2
WHERE (T1.PoNumber = T2.PoNumber) AND (T1.ReqSubmitDate BETWEEN '04/01/2005'
AND '04/30/2005')
GROUP BY T1.DataSource
/*---*/
The current resulting data is:
[Service Line] [Total Of PONumber] [04/2/2005] [04/9/2005] [04/16/2005]
[04/23/2005] [04/30/2005]
EVPN 4 NULL NULL 4 NULL NULL
MNS 526 NULL 209 313 NULL 4
/*---*/
Now, one of my tasks assign to me is to find the average cycle time for each
w per [Service Line]. This will include the following fields to the
query:
REQCreateDate DateTime,
REQCreateTime VarChar(10),
ReqSubmitTime VarChar(10),
ReqSubmitDate DateTime (This one is already used within the above query)
So, I'm thinking I need to concatinate the following columns, then get the
total number per w and derive the average:
T1.REQCreateDate + CAST(T1.REQCreateTime AS DATETIME) AS RC,
T1.ReqSubmitDate + CAST(T1.ReqSubmitTime AS DATETIME) AS RS
I hope I am making sense and you can help m understand this.
Thanks for taking the time though.
John.John,
If you can provide some sample data and also show
the exact results you want, it will be easier to help. You
may know exactly what "average cycle time" means, but
I don't. Sample data will also help to show why and how
you are storing values like REQCreateTime as VarChar(10),
since the time columns appear to be important.

it ether :(.
The Cycle Time is the Number of Minutes between ReqCreated Date/Time and
ReqSubmit Date/Time.
At the bottom of the my current message I have my newest version of the
query that at least shows the total Cycle Times per w. But I need to
show the averages, not the total.
Thanks very much for helping me.

Did you try using AVG() instead of SUM() ? To be safe from rounding
surprises, write any AVG() expression as AVG(1.0*(yourvalue)) if yourvalue
is an integer.
