Query To Merge Duplicate Records

Hello,

I have the following Query:

1    declare @StartDate char(8)
2    declare @EndDate char(8)
3    set @StartDate = '20070601'
4    set @EndDate = '20070630'
5    SELECT Initials, [Position],  DATEDIFF(mi,[TimeOn],[TimeOff]) AS ProTime
6    FROM LogTable WHERE
7    [TimeOn] BETWEEN @StartDate AND @EndDate AND
8    [TimeOff] BETWEEN @StartDate AND @EndDate
9    ORDER BY [Position],[Initials] ASC


The query returns the following data:

Position                                           Initials ProTime    
-------------------------------------------------- -------- -----------
ACAD                                               JJ       127        
ACAD                                               JJ       62         
ACAD                                               KK       230        
ACAD                                               KK       83         
ACAD                                               KK       127        
ACAD                                               TD       122        
ACAD                                               TJ       127        

  

What I'm having trouble with is the fact that I need to return a results that has the totals for each set of initials for each position.  For Example, the final output that I'm looking to get is the following:

Postition                       Initials                 ProTime

ACAD                           JJ                       189
ACAD                          KK                       440
ACAD                          TD                        122
ACAD                          TJ                         127

 Any assistance greatly appreciated.
