SQL translation from Access/VB/ADO to Oracle/VB/ADO

I have a sql string generated in a vb function that returns a sql string. Worked fine in Access but as it uses internal vb functions in a couple of places it fails in Oracle. If someone could point the error of my ways I'd appreciate the language lesson..
(I take no responsibility for the table design!.. existing app!)

Working Access String:
SELECT H.SSNO, CDbl([A.GIFTVAL]*-1) AS GVal, H.EMPNO, H.FNAME, H.LNAME FROM H1EMP H INNER JOIN AWARDS_AWARDS A ON A.EmpNo = H.EmpNo WHERE ((A.ORDERNO)='& CStr(6) &' AND
((A.BATCHKEY)=6) ORDER BY H.LNAME, H.FNAME;
Non-Working Oracle String:
SELECT H.SSNO, TO_NUMBER([A.GIFTVAL]*-1) AS GVal, H.EMPNO, H.FNAME, H.LNAME FROM H1EMP H INNER JOIN AWARDS_AWARDS A ON A.EmpNo = H.EmpNo WHERE ((A.ORDERNO)= TO_CHAR(6) & AND ((A.BATCHKEY)=6) ORDER BY H.LNAME, H.FNAME;
