How can i get LatLng out of a database to work in maps?

Question

Hello,
I am struggeling with a problem with a project of mine for several months now.
In Flash Builder i have a Flex Mobile Project with a list and on click, i want a map to show up.
What i try to do is, get the coordinates from a database and transport it to a map on a mobile device.
This is my sample code :
protected function onMapReady(event:MapEvent):void
                                        map.setCenter(new LatLng(53.207208,5.913611), 14, MapType.NORMAL_MAP_TYPE);
                                        var markerA:Marker = new Marker( new LatLng(53.207208,5.913611)  );
                                        map.addOverlay(markerA);
                                        map.addControl(new ZoomControl());
                                        map.addControl(new PositionControl());
                                        map.addControl(new MapTypeControl());
                                        startGPS();
I get my lat and lng from the database and push it to the next view.
On this view i  get the data as {data.lat} and  {data.lng}.
If i put this in a textfield it works:    <s:Label y="100" left="10" right="10" text="{data.lat},{data.lng}"/>
But if i try to put it in a new LatLng() like this: new LatLng({data.lat},{data.lng}), the marker doen't show in the map and i have errors in FlashBuilder.
Maybe my approach is wrong, so if you know a better way to do it i am open to it.
Can you help me to solve this problem.
I would be very gratefull if you would help me.
Sincerely, Gerard Weijer

Thank you very much!!!.. It works..
But now i have 2 markers and i want the route to be shown as an blue line in between the markers...
This code produces the 2 markers:
protected function onMapReady(event:MapEvent):void
                                        map.setCenter(new LatLng(data.lat,data.lng), 14, MapType.NORMAL_MAP_TYPE);
                                        var markerA:Marker = new Marker( new LatLng(data.lat,data.lng) );
                                        map.addOverlay(markerA);
                                        map.addControl(new ZoomControl());
                                        map.addControl(new PositionControl());
                                        map.addControl(new MapTypeControl());
                                        startGPS();
                              protected function startGPS():void {
                                        if(Geolocation.isSupported){
                                                  geoLocation = new Geolocation();
                                                  if(geoLocation.muted){
                                                  geoLocation.setRequestedUpdateInterval(3000);
                                                  geoLocation.addEventListener(GeolocationEvent.UPDATE, handleLocationRequest);     
                                        } else {
                                                 // turn on gps!
                              private function handleLocationRequest(event:GeolocationEvent):void {     
                                        map.setCenter(new LatLng(event.latitude,event.longitude));   
                                        var markerB:Marker = new Marker(
                                                  new LatLng(event.latitude,event.longitude));
                                        map.addOverlay(markerB);
