when I call GetClosestPlace() however, I get the error as stated above.

• xhr.open('Get', 'http://http://...
  - double "http://" in the URL.
• GetClosestRestaurant(location, distance, results, DisplayPlace);
  - location, distance, results and DisplayPlace are not defined at the point where you are calling this function.
• GetLatLong calls GetAddress, passing GetClosestRestaurant as the callback parameter. GetAddress then passes three parameters to the callback function, but your GetClosestRestaurant function requires four parameters.

_lat, _lng, _location, distance, results
function GetClosestRestaurant(_location, distance, results, callback) {

        _lat = _location.lat();
        _lng = _location.lng();

        var jdata = { lat: _lat, lng: _lng, distance: distance, results:results };

        var xhr = new XMLHttpRequest();
        xhr.onreadystatechange = function () {
            if (xhr.readyState < 4) {

                return;
            }
            if (xhr.status !== 200) {

                return;
            }
        };

        xhr.open('Get', "http://localhost:21311/myService.asmx/GetClosestPlace", true);
        xhr.setRequestHeader("Content-Type", "application/json;charset=UTF-8");

        xhr.send(JSON.stringify(jdata));
        callback(xhr.responseText);
    }

    GetClosestRestaurant(_location, distance, results, DisplayClosestRestaurant);

    function GetAddress(addr, callback) {
     location = "Some Location"; // Value returned from Google Map API
     distance = "5";
     results = "10";
    callback(location, distance, results);
    }

      var address = "123 SomeStreet, SomeCity, SomeState";
       GetAddress(address, GetClosestRestaurant)
    }
