WCF Error : Relative end point addresses

Um quite new to WCF . I think I have messed up a bit. So this is what I did so far and I ve hosted my WCF service in IIS

First the Contracts

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Web;
using System.Text;
using YangkeeServer.dto;

namespace YangkeeServer
   {

public class Service1 : IService1
{
    [WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "single")]
    public YangkeeTrailerDTO getTrailor()
    {
        return new YangkeeTrailerDTO()
        {
            loanFrom = "heaven"
        };
    }


    [WebInvoke(Method = "GET",
       ResponseFormat = WebMessageFormat.Json,
       UriTemplate = "datum/{id}")]
    public Test getName(string id)
    {
        return new Test()
        {
            Id = Convert.ToInt32(id) * 12,
            Name = "Leo Messi"
        };
    }
}
}

and this is my web.config file

<?xml version="1.0"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />

  </system.web>
  <system.serviceModel>
