INSERT INTO doesn't insert data in the database

Hi ,
I found my error in the data source (the path) in the ciode where I define the OleDbConnection.

Thanks anyway to both of you

HEre is the whole code for the button_click procedure Pankaj:

OleDbCommand command = new OleDbCommand();
  command.Connection = conn;
  label12.Text = Convert.ToString(p + 1);
command.CommandText = "Insert into PSOSTD ([SMAT11], [SKOM], [KOL], [CEN], [BRP], [DOK],[DATA], [SERBR1], [SERBR2], [MBRK], [IN]) values (?,?,?,?,?,?,?,?,?,?,?)";
  
  command.Parameters.AddWithValue("@SKOM", comboBox3.Text);
  command.Parameters.AddWithValue("@KOL", Convert.ToInt32(textBox4.Text));
  command.Parameters.AddWithValue("@CEN", Convert.ToInt32(label15.Text));
  command.Parameters.AddWithValue("@BRP", textBox1.Text);
  command.Parameters.AddWithValue("@DOK", "4");
  command.Parameters.AddWithValue("@DATA", dateTimePicker1.Value.Date);
  command.Parameters.AddWithValue("@SERBR1", "");
  command.Parameters.AddWithValue("@SERBR2", "");
  command.Parameters.AddWithValue("@MBRK", comboBox2.SelectedItem);
 if (radioButton1.Checked)
  {
  command.Parameters.AddWithValue("@IN", "J");
  }
  else if (radioButton2.Checked)
  {
  command.Parameters.AddWithValue("@IN", "A");
  }
  else
  {
  MessageBox.Show("Nemate izbrano dali kontrolorot e od JSP ili od agencija");
  comboBox2.Focus();
  }
 
 
  DataSet1 dset = new DataSet1();
  conn.Open();
  command.ExecuteNonQuery();
  OleDbDataAdapter oleDBDataAdapter1 = new OleDbDataAdapter(new OleDbCommand("Select * from PSOSTD order by SMAT11 asc", conn));
  dset.Clear();
  oleDBDataAdapter1.Fill(dset, "PSOSTD");

  OleDbDataAdapter oleDbAd2 = new OleDbDataAdapter();
  oleDbAd2.SelectCommand = new OleDbCommand();
  oleDbAd2.SelectCommand.Connection = conn;
  oleDbAd2.SelectCommand.CommandText = "SELECT p.BRP, p.SMAT11, m.IMAT, m.EM, p.KOL, m.CEN, MAT.MBR, p.IN from PSOSTD as p, SIFMAT as m, MATDAT AS MAT where p.SMAT11=m.SMAT11 and p.BRP=? order by BRP";
  oleDbAd2.SelectCommand.Parameters.AddWithValue("@BRP", textBox1.Text);
 
  oleDbAd2.SelectCommand.ExecuteNonQuery();
  dset.Clear();
  oleDbAd2.Fill(dset, "PSOSTD?");
  dataGridView1.DataSource = dset.Tables["PSOSTD?"].DefaultView;
  }
  catch(Exception ex)
  {
  MessageBox.Show(ex.ToString());
  }
  finally
  {
  conn.Close();
  }
