I have the below js that implements a google map with a looped through set of custom markers. I need each marker to have a different infowindow so when you click the marker you get the content that is relevant. At the minute it doesn't open the infowindow and doesn't give me an error in console

infowindow = new google.maps.InfoWindow();

    for(var i=0; i<google_map_item.length; i++)
    {
        latlon = new google.maps.LatLng(google_map_item[i].lat, google_map_item[i].lon)
        bounds.extend(latlon);
        var iconcolor = google_map_item[i].iconColor;
        marker = new google.maps.Marker({
            map: map,
            position: latlon,
            icon: ";chld=" + (i + 1) + "|"+iconcolor+"|000000",
            type: 'flat',
            icon_color: '#ff0000', 
            label_color: '#ffffff', 
            width: '20', 
            height: '20', 
            label_size: '11',
                            clickable: true
        });

                    google.maps.event.addListener(marker, 'click', function() {
                        //marker.info.open(map, this);
                        infowindow.setContent(this.latlon);
                        infowindow.open(map, this);
                    });


        map.fitBounds(bounds);
    }

var marker3 = new google.maps.Marker({
          map: map,                                                        
          icon: 'miniMarker.png',
          info: destArr[i][9],
          position: new google.maps.LatLng(destArr[i][7], destArr[i][8])
});
var infowindow3 = new google.maps.InfoWindow();
google.maps.event.addListener(marker3, 'mouseover', function () {
        infowindow3.setContent(this.info);                              
        infowindow3.open(map, this);                        
});

Working example with more then 20 markers and info window

The reference in the marker array was incorrect as outlined in this similar question
