    $(document).ready(function (){ 
        var sPath ="images/AppIcons/Vehicles/icon05.png,";
        var markers= new google.maps.Marker({
            position : new google.maps.LatLng(4.759915, -74.04083),
            map : map,
            icon : new google.maps.MarkerImage(+ sPath + null, null, null, new google.maps.Size(32, 32)),
            animation: google.maps.Animation.DROP,
            title : "buena"
        });
        var myLatlng = new google.maps.LatLng(0, 0);
        var mapOptions={zoom: 3,center: new google.maps.LatLng(4.590798,-74.084244),mapTypeId: google.maps.MapTypeId.ROADMAP };
        var map = new google.maps.Map(document.getElementById('map_canvas'), mapOptions);
        var marker = setMarkers(map);
        var infowindow = new google.maps.InfoWindow({Content : 'FM3200 - FM3200 20/01/2013 04:30:56 p.m. - Voltaje Externo - (Norte)Ubicacion Invalida In1:0 In2:0 In3:0 Batext:4.45V Vel:0 Odom:0 Ibutton:0 Oficina Principal Risk, Kmh: 0'});
        if (markers !='') {
            google.maps.event.addListener(marker, 'click', function() {
                infowindow.open(map,marker);
                /*if (marker.getAnimation() != null) {
                    marker.setAnimation(null);
                } else {
                    marker.setAnimation(google.maps.Animation.BOUNCE);
                }*/
            });
        }
    });
    function setMarkers(map,markers) {
        var marker =markers;
        if (marker !='') {
            return marker;
        }
    }

When play this code apear this message of error

Uncaught TypeError: Cannot read property '__e3_' of undefined main.js:18 

How can solved this error Thanks for your help..

1. Move the creation of map to the top of the function.

   Currently you use map as map-option for markers, where it’s expected to be a google.maps.Map-instance(but it’s undefined, because the map isn’t created yet)
