Need to sum 2 fields

Hi experts

i had a query based on oinv and inv1

in this 2 field i need to sum and should appear in single line

1. The DocTotal Filed

2. The U_Contract Values Filed

i had done it but its still showing the same data repeat wise

also need to filter the report From Docdate -  To Doc Date

The below attache is the Query

----------------------------------------------------------------------------------------------------

Select Distinct OINV.CARDCODE,OINV.CARDNAME,OINV.DOCDATE,Sum(OINV.DOCTOTAL) AS 'DocTotal',OCRD.U_ConStartDate 'ContStartDate',

OCRD.U_ConExpiryDate as 'ConExpiryDate',Sum(OCRD.U_ContractValues) as 'Contract Value'

FROM OINV

INNER JOIN INV1 ON OINV.DOCENTRY = INV1.DOCENTRY

INNER JOIN OCRD ON OINV.CARDCODE = OCRD.CARDCODE

WHERE INV1.TARGETTYPE <> 14 AND

OCRD.QryGroup1 = 'Y'

Group by OINV.CARDCODE,OINV.CARDNAME,OINV.DOCDATE,OCRD.U_ConStartDate,

OCRD.U_ConExpiryDate
