[AccessD] SQL String - Executed against Oracle by ADO

I am issuing the following SQL string against an Oracle 9i database, and 
it is erroring because of the Null.

strSQL is equal to:

INSERT INTO TBLLOADDATA 
        (LOADFILEID, A01, A02, A03, A04, A05, A06, A07, A08, A09, A10, 
A11, A12, A13, A14, A15, A16, A17, A18, A19, A20, A21, A22, A23, A24, A25, 
A26, A27, A28, A29, A30) 
        VALUES 
('83','CCC','N','8642378','2663099','8642378','2663099','AAAAAA','BBBBB','26630990','SP','317','20060201',Null,'0','0','1.212200000','20060203','VVV',
'B','YYY','150000.000000000','ZZZ','181830.000000000','1.212200000','.000000000','1.212200000','.000000000','.000000000','20060201','0 
       ')

If in Immediate window I issue strSQL = "INSERT.... " etc (effectively 
resetting the variable) it runs just fine

I do have a function that is returning the Null as a string  (I have also 
tried as a variant)

Does anyone know how I could do the same through code ?

Thank you for any help you can give.
