Error With C# Select Statement

hi i have copied this from my other page where it works fine and i cant understand what is going wrong! maybe one of your guys can point out what i cant see! herei s my code

string strOrderID = Request.QueryString["orderID"].ToString();int intOrderID = Convert.ToInt32(strOrderID);

int intCustID = Convert.ToInt32(Request.QueryString["qsnOrderCustID"].ToString());lblCustomerID.Text = Request.QueryString["qsnOrderCustID"].ToString();lblOrderID.Text = Request.QueryString["orderID"].ToString();

 

SqlConnection myConn = new SqlConnection("Data Source=xxxx;Initial Catalog=xxxx;User ID=xxxx;Password=xxxx");

//This is the sql statement.string sql = "SELECT [del_address], [del_post_code], [del_time] From tbl_del WHERE order_ID = " + intOrderID;

 

//This creates a sql command which executes the sql statement.SqlCommand sqlCmd = new SqlCommand(sql, myConn);

myConn.Open();SqlDataReader dr = sqlCmd.ExecuteReader();

//This reads the first result from the sqlReader

dr.Read();

try

{

 lblDelTime.Text = Convert.ToString(dr["del_time"].ToString);

lblDelAddy.Text = dr["del_address"].ToString();lblDelPCode.Text = dr["del_post_code"].ToString();if (lblDelAddy.Text != "")

{

lblDelDate.Visible = true;lblDelTime.Visible = true;

Label1.Visible = true;Label2.Visible = true;

}

}catch (Exception except)

{lblerror.Text = Convert.ToString(except);

}
