Please help

I have a table with the following information. As you can see that John Smith was checked 6 times, 2 times out of 6 he made errors, and only one was Critical.

DateProcessed      BundleCount      NumberQCed      ErrorsDesc      CriticalNonCritical      ProcessedBy
10/29/2013      97      1      No Errors      n/a      John Smith
10/31/2013      68      1      No Errors      n/a      John Smith
11/1/2013      30      1      No Errors      n/a      John Smith
11/14/2013      1      1      Error 1      Yes      John Smith
11/14/2013      1      1      Error 2      No      John Smith
10/24/2013      5      1      No Errors      n/a      John Smith

So i would like to have output like
Name         Total          ErrorsOnly         Critical
John Smith 6                2                         1

Here is a working example on your data...

CREATE TABLE #Test
(DateProcessed Date NULL,
BundleCount int NULL,
NumberQCed int NULL,
ErrorsDesc VARCHAR(10) NULL,
CriticalNonCritical VARCHAR(10) NULL,
ProcessedBy VARCHAR(30) NULL)


INSERT INTO #Test (DateProcessed,BundleCount,NumberQCed,ErrorsDesc, CriticalNonCritical,ProcessedBy)
Values ('10/29/2013', 97 ,1 ,'No Errors','n/a', 'John Smith'),
('10/31/2013',      68 ,     1  ,    'No Errors' ,    'n/a',      'John Smith'),
('11/1/2013',    30  ,    1  ,    'No Errors',      'n/a',      'John Smith'),
('11/14/2013',      1,        1,      'Error 1' ,     'Yes',     'John Smith'),
('11/14/2013' ,     1,      1    ,  'Error 2'   ,   'No'     , 'John Smith'),
('10/24/2013',      5 ,     1     , 'No Errors'  ,    'n/a'   ,   'John Smith')

SELECT *
FROM #Test

SELECT ProcessedBy, SUM(Total) AS Total, SUM(ErrorsOnly) AS ErrorsOnly, SUM(Critical) AS Critical
FROM
(
SELECT ProcessedBy, COUNT(*) AS Total,
CASE WHEN ErrorsDesc <> 'No Errors' THEN 1 ELSE 0 END AS ErrorsOnly,
CASE WHEN CriticalNonCritical = 'Yes' THEN 1 ELSE 0 END AS Critical
FROM #Test
GROUP BY ProcessedBy,ErrorsDesc, CriticalNonCritical
) a
GROUP BY a.ProcessedBy
