Hello.
I wrote the following code to display markers. There are 2 buttons which show Next or Previous Infowindow for markers. But problem is that InfoWindows are not shown using
google.maps.event.trigger
Can someone help me with this problem. Thank you.
Here is code:

var infowindow;
var map;
var bounds;
var markers = [];
var markerIndex=0;
function initialize() {
var myLatlng = new
google.maps.LatLng(41.051407, 28.991134);
var myOptions = {
zoom: 5,
center: myLatlng,
mapTypeId:
google.maps.MapTypeId.ROADMAP
}
map = new
google.maps.Map(document.getElementById("map_canvas"), myOptions);
markers = document.getElementsByTagName("marker");
for (var i = 0; i < markers.length; i++) {
var latlng = new
google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),
parseFloat(markers[i].getAttribute("lng")));
var marker = createMarker(markers[i].getAttribute("name"), latlng, markers[i].getAttribute("phone"), markers[i].getAttribute("distance"));
}
rebound(map);
}
function createMarker(name, latlng, phone, distance) {
var marker = new
google.maps.Marker({position: latlng, map: map});
var myHtml = "<table style='width:100%;'><tr><td><b>" + name + "</b></td></tr><tr><td>" + phone + "</td></tr><tr><td align='right'>" + distance + "</td></tr></table>";
google.maps.event.addListener(marker, "click", function() {
if (infowindow) infowindow.close();
infowindow = new
google.maps.InfoWindow({content: myHtml});
infowindow.open(map, marker);
});
return marker;
}
function rebound(mymap){
bounds = new
google.maps.LatLngBounds();
for (var i = 0; i < markers.length; i++) {
bounds.extend(new
google.maps.LatLng(parseFloat(markers[i].getAttribute("lat")),parseFloat(markers[i].getAttribute("lng"))));
}
mymap.fitBounds(bounds);
}
function showNextInfo()
{
