if (dt.Rows.Count > 0)
{
DataTable dtl = new DataTable();
string left = "SELECT * FROM Registration_Master WHERE side='LEFT'";
dtl = DBHelper.SQLHelper.getTable(left.ToString());
int count_mem = Convert.ToInt32(dtl.Rows[0]["count_mem"]);
count_mem++;
com.Connection = con;
com.CommandText = "UPDATE Counter SET leftcount =" + count_mem + "";
com.CommandType = CommandType.Text;
com.ExecuteNonQuery();
DataTable dtr = new DataTable();
string right = "SELECT * FROM Registration_Master WHERE side='RIGHT'";
dtr = DBHelper.SQLHelper.getTable(right.ToString());
if (dtr.Rows.Count > 0)
{
int count1 = Convert.ToInt32(dtr.Rows[0]["count_mem"]);
count1++;
com = new SqlCommand();
com.Connection = con;

DataTable dtcount = new DataTable();
string query = "SELECT * FROM Counter";
dtcount = DBHelper.SQLHelper.getTable(query.ToString());
if (dtcount.Rows.Count > 0)
{
if (dtcount.Rows[0]["leftcount"] == dtcount.Rows[0]["rightcount"])
{
int count2 = Convert.ToInt32(dtl.Rows[0]["count_mem"]);
count2++;
com = new SqlCommand();
