Problem with dropdown after binding arraylist

Hi folks.  I have a dropdown that I have successfully bound to arraylist.  My problem is that when I select an option, my insert statement is showing there is no value selected.  I am querying a table for the ratings that are to populate the dropdown.  The result is a string list, so I am interating thru the list to populate the arralylist, then binding to the dropdown. Please advise.  My code is below:


bool bIsError = false;
            alRatings = new ArrayList(1); // create arraylist to hold Possible Rating Responses
            alRatings.Add("");
            SqlConnection con = new SqlConnection(strConnection);
             string tempOption = "";
            try
            {
                SqlCommand cmd = con.CreateCommand();
                cmd.CommandText = "SELECT DISTINCT FormatType FROM t_Questions Where FormName= '" + formFilter + "' AND SeqNumber= " + tempSeqNum;
                con.Open();
                SqlDataReader dr = cmd.ExecuteReader();

                if (dr.HasRows)
                {
                    while (dr.Read())
                    {
                        tempOption = dr["FormatType"].ToString();
                       
                    }
                 
                   
                    string[] strtemp = tempOption.Split(';');
                        foreach (string s in strtemp)
                        {
                            alRatings.Add(s);
                        }
                        alRatings.TrimToSize();
                    Rating.DataSource = alRatings;
                    Rating.DataBind();
                    con.Close();
                }
                else
                {
                    ........
                }
            }
            catch (Exception err)
            {.....
          }

INSERT Statement:

cmdInsert2.CommandText = "INSERT INTO t_Answers(CNTRL_NUM, Date, User, SeqNumber, " +
                        " Response, Comment)  VALUES( '" + CNTRL_NUM.Text + "', '" + Date.Text + "', '" + User.Text + "', " + SeqNumber.Text + ", '" + Rating.SelectedValue + "', '" + txtCmt.Text + "' );";
