MySqlAdapter.Fill Error...

Hello,

I got an error message every time when I run the code below. The code is
below, the last line is where the error occurs, could anybody
tell me why and how to solve it?
Thanks a lot!!

for int i=x i<y do (

MySqlCommand select = new MySqlCommand();
select.Connection = conn;
System.Console.WriteLine(select.Connection.State);
select.Parameters.Add("?Start", startDate);
select.Parameters.Add("?End", endDate);
MySqlDataAdapter adapter = new MySqlDataAdapter(select);
select.CommandText =
"SELECT * FROM ticket WHERE Processed = 1 AND CreateTime <= ?End AND " +
"(_EndTime IS NULL OR _EndTime >= ?Start) AND Network = '" + network +
"' ORDER BY TicketNo";
DataSet tickets = new DataSet();
adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
adapter.MissingMappingAction = MissingMappingAction.Passthrough;
adapter.Fill(tickets, "Ticket");
System.Console.WriteLine("after filling tickets...");
ProgressDialog.Step();
select.CommandText =
"SELECT m.* FROM ticket t, milestone m WHERE Processed = 1 AND
t.CreateTime <= ?End AND " +
"(t._EndTime IS NULL OR t._EndTime >= ?Start) AND t.Network = '" +
network + "' " +
"AND t.ticketno = m.ticketno ORDER BY t.TicketNo";
adapter.MissingSchemaAction = MissingSchemaAction.AddWithKey;
adapter.MissingMappingAction = MissingMappingAction.Passthrough;
adapter.Fill(tickets,"Milestone");
-< Error appears here....!!!!!!


) end loop
