I've got a complexion with this JavaScript. I've done several research but yet to succeed. Anyone?

<script type="text/javascript">
var map;

function init() {
// Create the map object
map = new OpenLayers.Map({
        allOverlays: true,
        controls: [
            new OpenLayers.Control.Navigation(),
            new OpenLayers.Control.PanZoom(),
        ]
    });
    var osm_layer = new OpenLayers.Layer.OSM();
    map.addLayer(osm_layer);

map.setCenter(
            new OpenLayers.LonLat(mylon,mylat).transform(
                new OpenLayers.Projection("EPSG:4326"),
                map.getProjectionObject()
            ), 12
        ); */        
}

var KMLURL = 'myfile.kml?' + Math.random();

var MyKmlLayer= new OpenLayers.Layer.Vector("This Is My KML Layer", {
        //Set your projection and strategies//
        projection: new OpenLayers.Projection("EPSG:4326"),
        strategies: [new OpenLayers.Strategy.Fixed()],
        //set the protocol with a url//
        protocol: new OpenLayers.Protocol.HTTP({
            //set the url to your variable//
            url: KMLURL,
            //format this layer as KML//
            format: new OpenLayers.Format.KML({
                //maxDepth is how deep it will follow network links//
                maxDepth: 1,
                //extract styles from the KML Layer//
                extractStyles: true,
                //extract attributes from the KML Layer//
                extractAttributes: true
            })
        })
    });

window.setInterval(UpdateKmlLayer, 5000, MyKmlLayer);

function UpdateKmlLayer(layer) {
        //setting loaded to false unloads the layer//
        layer.loaded = false;
        //setting visibility to true forces a reload of the layer//
        layer.setVisibility(true);
        //the refresh will force it to get the new KML data//
        layer.refresh({ force: true, params: { 'key': Math.random()} });
    }
}
</script>

Thank you in advance.

First, this isn't really an OpenStreetMap question, but an OpenLayers one (or even just a JavaScript one) -- you may get an answer by asking in a forum for OpenLayers.

Even then you should try to come up with a better worded question, rather than simply dumping your code and expecting everyone to find the problem. State what you've tried that didn't work, and what results you got instead.
