Accessing Access Data in Navision.

Dear All,
While accessing the data from Access i have written the following code in Navision i have two problems in the following code

1) when the data is pulled the first character of the first field is always missing like my first field is Empcode then if code is MP0001 then only P0001 is pulled same is for all the rows.

2) I have three fields in the table both in the Access and the navision table When Ever i write the query 'Select EmpCode, EmpName From Employee' the following error is flashed out "Call to the member Item Failed Fields written the following message: Item Cannot be found in the corresponding collection to the requested name." But it wrks properly when i select all the fields of the table.

My Code is

Constr := 'Provider=Microsoft.Jet.OLEDB.4.0; Data Source=C:\Access To Navision\Amantest.mdb;' +
'User Id=admin; Password=;';
StrSql := 'Select EmpCode, EmpName From Employee';

CREATE(varRecordSet);
varRecordSet.Open(StrSql, Constr);
varRecordSet.MoveFirst;
RecordVar.OPEN(50001);
REPEAT
varFldCollection := varRecordSet.Fields;
RecordVar.RESET;
RecordVar.INIT;
FOR i := 1 TO RecordVar.FIELDCOUNT DO BEGIN
FieldVar := RecordVar.FIELDINDEX(i);
FieldVar.VALIDATE(varFldCollection.Item(i-1).Value);
END;
RecordVar.INSERT;
cFlag := 1;
varRecordSet.MoveNext
UNTIL varRecordSet.EOF = TRUE;
IF cFlag = 1 THEN
MESSAGE('Data Imported');
varRecordSet.Close;
RecordVar.CLOSE;
CLEAR(varRecordSet);
CLEAR(RecordVar);

Please Help... #-o
