Number of SQL in MS Access

I have a table called [Review Results] that looks something like this:

[Reviewed By]....[Review Date]....[Corrective Action]....[CAR]
John.............1/1/2011.........yes....................yes
John.............2/5/2011.........No.....................yes
John.............2/24/2011........yes....................yes
Bobby............1/1/2011.........No.....................No
Bobby............3/1/2011.........yes....................No

I am trying to display a number from a [Corrective Action] = yes

reviewer for a specified period, as well as a number [CAR] = yes

from a reviewer for a specified period. I tried using the following SQL, but it doesn't give the correct output:

select 
[Reviewed By],
Count(IIF([Corrective Action] = yes, 1,0)) as [CAMBRs],
Count(IIF([CAR] = yes,1,0)) as [CARs]

from [Review Results] 

where [Review Date]  between #1/1/2011# and #3/1/2011#

group by
[Reviewed By]

Can anyone point me in the right direction using SQL?

select 
[Reviewed By],
SUM(IIF([Corrective Action] = "yes", 1,0)) as [CAMBRs],
SUM(IIF([CAR] = "yes",1,0)) as [CARs]

from [Review Results] 

where [Review Date]  between #1/1/2012# and #3/1/2012#

group by
[Reviewed By]

Perhaps something like this:



select 
   [Reviewed By],
   SUM(IIF([Corrective Action] = True, 1,0)) as [CAMBRs],
   SUM(IIF([CAR] = True,1,0)) as [CARs]

from [Review Results] 

where [Review Date]  between #1/1/2012# and #3/1/2012#

group by
[Reviewed By]
