Select with Nulls

My attached code works fine as long as the @DealID exists in the table

But if it doesn't, columns are shown with empty data row.
 Screenprint
What I would like returned is the DealID and nulls like this
 Screenprint2
Declare @DealID int
Set @DealID = 1988

Select	IsNull(Substring(afsSource,4,4),0) dealID, 
		Sum(Case When afsTransaction = 0 Then 1 Else 0 End) AS Zeroes,   
		Sum(Case When afsTransaction <> 0 Then 1 Else 0 End) AS NonZeroes  
From	proc_cfa.dbo.P_AvailableForSale
Where	substring(afsSource,4,4) = @DealID
Group By substring(afsSource,4,4)
order by Cast(substring(afsSource,4,4) as Int)

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

like this use left outer join

Declare @DealID int
Set @DealID = 1988

Select      x.dealID
       ,Sum(Case When afsTransaction = 0 Then 1 Else 0 End) AS Zeroes,  
       ,Sum(Case When afsTransaction <> 0 Then 1 Else 0 End) AS NonZeroes  
From (select @dealid as dealid) as x
left outer join      proc_cfa.dbo.P_AvailableForSale
 on substring(afsSource,4,4) = x.DealID
Group By x.dealid
order by 1
