Delphi 1.0 - ODBC and JET 2.0 - Error 1003 when writing to dB

        Error messages are given whein any write operations are performed on my
grid control. The error message is :   "General SQL Error[Microsoft][ODBC
Access Driver]Jet Error 1003 Returned

I am somewhat baffled. Any ideas as I am running out of time.
