Help with Case Statement

I only want to return 1 row per "Owner_Name". Right now my statement is displaying NULLs for each Report_GroupID that is present in the database;

select  owner_name as 'Name',
           case when report_groupid = 5 then sum(qty) end as 'RG 5',
           case when report_groupid = 1 or report_groupid = 2 then sum(qty) end as 'RG 1 & 2'
from check_item_record
where storeid = 14
and check_file_date = '7/6/2009'
group by owner_name, report_groupid,  qty

Here is how it is displaying:

Name            RG 5         RG 1 & 2
User1            15            Null
User1            Null         19

I want it to display like this:
Name            RG 5         RG 1 & 2
User1            15            19

Any ideas here?

Try like this:
+Move aggregate outside of case statement.
+Only group by owner_name.
(note you can use in for multiple values of same column)
select  owner_name as 'Name',
sum(case when report_groupid = 5 then qty end) as 'RG 5',
sum(case when report_groupid in (1,2) then qty end) as 'RG 1 & 2'
from check_item_record
where storeid = 14
and check_file_date = '7/6/2009'
group by owner_name

SELECT Owner_name , sum(qty1) as 'RG 5', SUM(qty2) as 'RG 1 & 2'
FROM (
select  owner_name as 'Name',
           case when report_groupid = 5 then qty ELSE 0 end qty1 ,
           case when report_groupid = 1 or report_groupid = 2 then qty else 0 end as qty2  
from check_item_record
where storeid = 14
and check_file_date = '7/6/2009' )

How about:

Select  owner_name as 'Name',
        sum(case when report_groupid = 5 then qty Else 0 end) as 'RG 5',
        sum(case when report_groupid in (1,2) then qty Else 0 end) as 'RG 1 & 2'
from    check_item_record
where   storeid = 14
        and check_file_date = '7/6/2009'
group by owner_name
