Create Record through a Web Form

I have created a web form in Visual Studio that when I run locally works great. It takes the input fields and creates a contact in the CRM. I can use the html to put the web form up on a website but then that is where I am stuck and can't seem to find any more information. Where am I connecting the server side code (shown below) so that it captures the input values from the form once published on our website.

I followed this link here: http://blogs.msdn.com/b/crminthefield/archive/2011/05/18/how-to-create-a-simple-webpage-leveraging-the-crm-2011-iorganizationservice-web-service.aspx to create this. I also copied the html into a web resource and the form successfully shows up but again the code to actually create the contact isn't connecting so I'm not sure how to do that.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.ServiceModel.Description;
using Microsoft.Xrm.Sdk.Client;
using System.Net;
using Microsoft.Xrm.Sdk;

namespace CRMContactDataEntry
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {
            //Authenticate using credentials of the logged in user;       

            ClientCredentials Credentials = new ClientCredentials();

            Credentials.Windows.ClientCredential = CredentialCache.DefaultNetworkCredentials;

            //This URL needs to be updated to match the servername and Organization for the environment.

            Uri OrganizationUri = new Uri("http://server/name/XRMServices/2011/Organization.svc");

            Uri HomeRealmUri = null;



            //OrganizationServiceProxy serviceProxy;       

            using (OrganizationServiceProxy serviceProxy = new OrganizationServiceProxy(OrganizationUri, HomeRealmUri, Credentials, null))
            {

                IOrganizationService service = (IOrganizationService)serviceProxy;



                //Instantiate the contact object and populate the attributes.

                Entity contact = new Entity("contact");

                contact["firstname"] = txtFirstName.Text.ToString();

                contact["lastname"] = txtLastName.Text.ToString();

                contact["emailaddress1"] = txtEmailAddress.Text.ToString();

                contact["telephone1"] = txtPhoneNumber.Text.ToString();

                Guid newContactId = service.Create(contact);



                //This code will clear the textboxes after the contact is created.

                txtFirstName.Text = "";

                txtLastName.Text = "";

                txtEmailAddress.Text = "";

                txtPhoneNumber.Text = "";

            }
        }
    }
}

Thanks for any help!
