  5.             SqlParameter debit = new SqlParameter("@debit", SqlDbType.Decimal);  
  6.             SqlParameter credit = new SqlParameter("@credit", SqlDbType.Decimal);              
  7.             comm.Parameters.Add(debit);  
  8.             comm.Parameters.Add(credit);              
  9.             debit.Value = Convert.ToDecimal(txtDebit.Text, CultureInfo.InvariantCulture);  //its stucks here
  10.             credit.Value = Convert.ToDecimal(txtCredit.Text, CultureInfo.InvariantCulture);  //its stucks here
  11.             comm.Connection = conn;

  15.                 if (MessageBox.Show("Are you sure to save?""Save", MessageBoxButtons.YesNo) == DialogResult.Yes)  
  16.                 {  
  17.                     try  
  18.                     {  
  19.                         comm.ExecuteNonQuery();
