Query with Start Date and End Date

Question

Dear Members,
I have done a basic query on to get a report on Sales Invoices processed in a given period with the General Ledger account they were posted to. Minor hassle is that to change the dates, I have to go into the script (see extract below) and change dates manually, save query etc.
Is there a way to have the query, when selected to run, pop up with window, allowing user to input say "start date" and "finish date". I imagine it will require some complex addition to the script below, any assistance will be appreciated.
Regards
Raj
SELECT T1.[DocNum] AS 'Document Number', T1.[DocDate] AS 'Posting Date', T0.[AcctCode] AS 'Account Code', T0.[Dscription] AS 'Item/Service Description', T0.[LineTotal] AS 'Row Total' FROM  [dbo].[INV1] T0  INNER  JOIN [dbo].[OINV] T1  ON  T1.[DocEntry] = T0.[DocEntry]   WHERE T1.[DocDate] > (CONVERT(DATETIME, '20110801', 112) )  AND  T1.[DocDate] < (CONVERT(DATETIME, '20110831', 112) )

Hi Raj,
try this:
/*SELECT FROM [dbo].[OINV] T0*/
declare  @StartDate as datetime
/* WHERE */
set @StartDate = /* T0.DocDate */ '[%0]'
/*SELECT FROM [dbo].[OINV] T1*/
declare  @EndDate as datetime
/* WHERE */
set @EndDate = /* T0.DocDate */ '[%1]'
SELECT T1.DocNum AS 'Document Number', T1.DocDate AS 'Posting Date', T0.AcctCode AS 'Account Code', T0.Dscription AS 'Item/Service Description', T0.LineTotal AS 'Row Total'
FROM dbo.INV1 T0 INNER JOIN dbo.OINV T1 ON T1.DocEntry = T0.DocEntry WHERE T1.DocDate > @StartDate AND T1.DocDate < @EndDate
Thanks,
