Stock closing balance report: per day

Question

Hi
I wonder if someone could help.
I require a report that will show me the closing stock balance over a specified period, but I want it to show the closing balance on each day, even if there is no movement.
I have used, and adapted, the following query from another thread. However I want it to show data for each day within the time period.
Thanks, Andy
Declare @FromDate Datetime
Declare @ToDate Datetime
Declare @Group nvarchar(10)
Set @FromDate = (Select min(S0.Docdate) from dbo.OINM S0 where S0.Docdate >='[%0]')
Set @ToDate = (Select max(S1.Docdate) from dbo.OINM s1 where S1.Docdate <='[%1]')
Set @Group = (Select s2.ItmsGrpCod from dbo.OITB S2 Where S2.ItmsGrpNam = '[%2]')
Select
a.Itemcode,
min(a.Dscription),
((sum(a.[Opening Balance]) + sum(a.[IN])) - Sum(a.OUT)) as Closing
from(
Select
N1.Itemcode,
N1.Dscription,
(sum(N1.inqty)-sum(n1.outqty)) as [Opening Balance],
0 as [IN],
0 as OUT
From dbo.OINM N1
Where
N1.DocDate < @FromDate
Group By
N1.ItemCode,N1.Dscription
Union All
select
N1.Itemcode,
N1.Dscription,
0 as [Opening Balance],
sum(N1.inqty) as [IN],
0 as OUT
From dbo.OINM N1
Where
N1.DocDate >= @FromDate and N1.DocDate <= @ToDate and
N1.Inqty >0
Group By
N1.ItemCode,N1.Dscription
Union All
select
N1.Itemcode,
N1.Dscription,
0 as [Opening Balance],
0 as [IN],
sum(N1.outqty) as OUT
From dbo.OINM N1
Where
N1.DocDate >= @FromDate and N1.DocDate <=@ToDate and
N1.OutQty > 0
Group By
N1.ItemCode,N1.Dscription) a, dbo.OITM I1
where
a.ItemCode=I1.ItemCode and
I1.ItmsGrpCod = @Group
Group By
a.Itemcode
Having sum(a.[Opening Balance]) + sum(a.[IN]) + sum(a.OUT) > 0
Order By a.Itemcode

No, not entirely.  It does show Ins and Out, but only days where there is an In or an Out and it also show ALL the Ins and Outs on one day.
I need the report to show me just the closing balance for each day, and also every day even if there is no In or Out.  Basically I need the query above to show me each day rather than the aggregate for the whole date period.
