I have difficulties understanding this error... I dont quite understand why its not a function....

angular.module('mkApp').factory('mkService', function ($http, $log) {

  function getLookUp(successcb) {

    $http = ({

        method: 'GET',

        url: 'api/Entries/'



    }).success(function (data, status, header, config) {

        successcb(data);

    }).

    error(function (data, status, header, config) {

        $log, warn(data, status, header, config);

    });

  };



  return {

    lookUp: getLookUp

  }

});



angular.module('mkApp').controller('mkControler', function ($scope, mkService) {

  mkService.lookUp(function (data) {

    $scope.ddl = data;

    console.log(ddl);



  });

});

And here is my HTML

<div ng-app=mkApp>

    <div ng-controller=mkControler>            

       <table>

           <tr>

               <td> First Name</td>

               <td> Last Name</td>

           </tr>

           <tr>

               <td><input type=text /></td>

               <td><input type=text /></td>

           </tr>

           <tr>

               <td>

                   <select></select>

               </td>

           </tr>

       </table>



    </div>

</div>

My idea is to use data to populate drop down. It does bring me XML back.
Any help please i've been looking everywhere now.
Thank you.
