hi everyone, im having some problem when im trying to add a new workflow to contour, im using the metod here described but is not working for me.

http://our.umbraco.org/wiki/how-tos/extending-contour,-sending-email-dependent-on-form-selection

i create a new class and added to the bin folder in umbraco, the code of the class is this one:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using Umbraco.Forms.Core;
using Umbraco.Forms.Core.Enums;
using Umbraco.Forms.Data.Storage;
using System.Xml;
using System.Xml.XPath;
using Umbraco.Forms.Core.Attributes;
using umbraco.BusinessLogic;

namespace SendContourEmail
{
    public class SendContourEmail : WorkflowType
    {

        // These regions set the fields in for new/cutom workflow you are wanting to create

        [Setting("EmailLookUpField", description = "Enter the receiver email lookup field", control = "Umbraco.Forms.Core.FieldSetting.TextField")]
        public string EmailLookUpField { get; set; }

        [Setting("EmailFrom", description = "Email from field alias that contains email address", control = "Umbraco.Forms.Core.FieldSetting.TextField")]
        public string EmailFrom { get; set; }

        [Setting("Subject", description = "Enter the subject", control = "Umbraco.Forms.Core.FieldSetting.TextField")]
        public string Subject { get; set; }

        [Setting("Message", description = "Enter the intro message", control = "Umbraco.Forms.Core.FieldSetting.TextArea")]
        public string Message { get; set; }

        [Setting("ErrorEmailAddress", description = "Error logging email", control = "Umbraco.Forms.Core.FieldSetting.TextField")]
        public string ErrorEmailAddress { get; set; }

        public override List<Exception> ValidateSettings()
        {
            List<Exception> l = new List<Exception>();
            if (string.IsNullOrEmpty(EmailLookUpField))
                l.Add(new Exception("'Email Look up field' setting not filled out'"));

            if (string.IsNullOrEmpty(Message))
                l.Add(new Exception("'Message' setting not filled out'"));

            return l;
        }

        private const string LookUpFieldXpath = "//fields/child::* [caption = '{0}']";

        // Generates the new workflow details for Contour in the workflow dropdown in Contour
        public SendContourEmail()
        {
            // Need to generate a new guid for the new custom workflow - add your own GUID
            this.Id = new Guid("55C192F4-65FB-11E0-8798-CF7DDFD72085");
            this.Name = "Send Custom Email";
            this.Description = "Send Email to the person who fill the form";
        }


        public override WorkflowExecutionStatus Execute(Record record, RecordEventArgs e)
        {
            try
            {
                RecordsViewer viewer = new RecordsViewer();
                XmlNode xml = viewer.GetSingleXmlRecord(record, new XmlDocument());

                XPathNavigator navigator = xml.CreateNavigator();
                XPathExpression selectExpression = navigator.Compile("//fields/child::*");
                selectExpression.AddSort("@pageindex", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Number);
                selectExpression.AddSort("@fieldsetindex", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Number);
                selectExpression.AddSort("@sortorder", XmlSortOrder.Ascending, XmlCaseOrder.None, "", XmlDataType.Number);

                XPathNodeIterator nodeIterator = navigator.Select(selectExpression);

                string list = "<dl>";

                while (nodeIterator.MoveNext())
                {


                    list += "<dt><strong>" + nodeIterator.Current.SelectSingleNode("caption").Value + ": </strong><dt><dd>";
                    XPathNodeIterator values = nodeIterator.Current.Select(".//value");
                    while (values.MoveNext())
                        list += values.Current.Value.Trim() + "<br/>";
                    list += "</dd>";
                }

                list += "</dl>";

                string body = "<p>" + Message + "</p>" + list;

                IEnumerable<string> emails = GetEmailAddressesViaLookUp(xml, body);

            }
            catch (Exception ex)
            {
                LogError(ex.ToString());
            }
            return WorkflowExecutionStatus.Completed;
        }

        private IEnumerable<string> GetEmailAddressesViaLookUp(XmlNode xml, string emailBody)
        {
            // EmailLookUpField - this is the field which we have specified in the workflow that has the email address 
            // values assigned to them, in our case the "Sectors" checkbox list.
            string xpath = string.Format(LookUpFieldXpath, EmailLookUpField);
            string fromEmailXpath = string.Format(LookUpFieldXpath, EmailFrom);
            var addresses = new List<string>();
            XmlNode destiniationIds = xml.SelectSingleNode(xpath);
            XmlNode fromEmail = xml.SelectSingleNode(fromEmailXpath);

            XmlNode emailFromNode = fromEmail.SelectSingleNode("values/value");
            EmailFrom = emailFromNode.InnerText;

            if (destiniationIds != null)
            {
                // Loops through the the List of emails and sends an email to each department
                IEnumerable<string> emails = ExtractSectorsFromNodeXml(destiniationIds);
                foreach (string email in emails)
                {
                    SendMail(email, Subject, emailBody);
                }
            }
            return addresses;
        }

        private IEnumerable<string> ExtractSectorsFromNodeXml(XmlNode destinations)
        {
            var ids = new List<string>();
            XmlNodeList destinationNodes = destinations.SelectNodes("values/value");
            if (destinationNodes != null)
            {
                foreach (XmlNode destinationNode in destinationNodes)
                {
                    if (destinationNode.Attributes != null)
                        ids.Add(destinationNode.InnerText);
                }
            }
            return ids;
        }

        private void SendMail(string to, string subject, string message)
        {
            var m = new System.Net.Mail.MailMessage
            {
                From = new System.Net.Mail.MailAddress(EmailFrom),
                Subject = subject,
                IsBodyHtml = true
            };

            m.To.Add(to);

            m.Body = message;
            var s = new System.Net.Mail.SmtpClient("localhost");
            s.Send(m);
        }

        private void LogError(string ErrorMessage)
        {
            Log.Add(LogTypes.Error, 0, ErrorMessage);
            if (ErrorEmailAddress != string.Empty)
            {
                SendMail(ErrorEmailAddress, "Contour custom workflow dmc lookup error", ErrorMessage);
            }
        }


    }


}

at the end i only have the workflow form created with this but there is no email sent when i create a new field called email and put an email there to reaply Approved to the person who fill the form

and this is the image of the created workflow when i acces workflow in the backend of contour

thanks a lot for any help, i feel lost with this subject.

IMPORTANT NOTE: the only change that i did in the original code of the class was change "emailAdress" for "email" based on the case that i cant compile the class without having any errors.
