if (rdk.Checked)
{
Response.Write(ds.Tables["qAnswer"].Rows[a][0].ToString() + "<br>");
string qDetail = ds.Tables["qAnswer"].Rows[a][0].ToString();
//***********************************************
commandText1 = @"select qCount from qAnswer WHERE qAnswerDetail = '" + qDetail + "'";
SqlDataAdapter da1 = new SqlDataAdapter(commandText1, connectionString);
DataSet ds1 = new DataSet();
da1.Fill(ds1, "qCount");
int updateCount = Convert.ToInt32(ds1.Tables["qCount"].Rows[0][0].ToString());
//***********************************************
//commandText2 = @"UPDATE qAnswer SET qCount = '" + (updateCount + 1) + "' WHERE qAnswerDetail = '" + qDetail + "'";
//SqlDataAdapter da2 = new SqlDataAdapter(commandText2, connectionString);
