Total Sales by BP by Date Query

Hello,

I am looking to change this query to have the sum of all invoices per BP rather than listing the totals of each invoice.

SELECT T0.[DocNum], T0.[CardCode], T0.[CardName], T0.[TaxDate], T0.[DocTotal], T1.[SlpName],T3.[State2] FROM [dbo].[ORDR]  T0 INNER JOIN [dbo].[OSLP]  T1 ON T0.[SlpCode] = T1.[SlpCode] INNER JOIN [dbo].[OCRD]  T3 ON T0.[CardCode] = T3.[CardCode] WHERE T0.[TaxDate] between [%0] and [%1] ORDER BY T0.[CardName]

What do I need to change to make it show the total for the date range selected and not each individual invoice total?

Thanks for the help,

Ben
