Writing To Database

 hi,
I'm trying to write to a database from a web page. The code is throwing back no errors but it just isn't writing to the database. Am I missing something?
 
void SubmitDetails(Object s, EventArgs e)
    {
        SqlConnection objConn = new SqlConnection(ConfigurationManager.AppSettings["ConnectionString"]);
        SqlCommand objCmd;
       
        objCmd = new SqlCommand(
            "INSERT INTO Member_Information (Name, Address_Line_1, Address_Line_2, Address_Line_3, Email_Address, Contact_Number, " +
            "Password, Name_Of_Bank, Account_Number, Sort_Code, Bank_Address_Line_1, Bank_Address_Line_2, Bank_Address_Line_3) " +
            "VALUES (@Name, @Address_Line_1, @Address_Line_2, @Address_Line_3, @Email_Address, @Contact_Number, " +
            "@Password, @Name_Of_Bank, @Account_Number, @Sort_Code, @Bank_Address_Line_1, @Bank_Address_Line_2, @Bank_Address_Line_3)", objConn);
        objCmd.Parameters.AddWithValue("@Name", txtName.Text);
        objCmd.Parameters.AddWithValue("@Address_Line_1", txtAL1.Text);
        objCmd.Parameters.AddWithValue("@Address_Line_2", txtAL2.Text);
        objCmd.Parameters.AddWithValue("@Address_Line_3", txtAL3.Text);
        objCmd.Parameters.AddWithValue("@Email_Address", txtEmail.Text);
        objCmd.Parameters.AddWithValue("@Contact_Number", txtContact.Text);
        objCmd.Parameters.AddWithValue("@Password", txtPassword.Text);
        objCmd.Parameters.AddWithValue("Name_Of_Bank", txtBank.Text);
        objCmd.Parameters.AddWithValue("Account_Number", txtAN.Text);
        objCmd.Parameters.AddWithValue("@Sort_Code", txtSort.Text);
        objCmd.Parameters.AddWithValue("@Bank_Address_Line_1", txtBA1.Text);
        objCmd.Parameters.AddWithValue("@Bank_Address_Line_2", txtBA2.Text);
        objCmd.Parameters.AddWithValue("@Bank_Address_Line_3", txtBA3.Text);
        objConn.Open();
        objCmd.ExecuteNonQuery();
        objConn.Close();
    }
