I've been trying to implement the markers on Layer.Vector adapting the code from the example you provided. I haven't gotten to the point of adding in the conditional statement yet, but I keep getting and error in the show map function at the var = feat line, saying that OpenLayers isn't defined. Jslint tells me this is because OpenLayers hasn't been defined yet. Now, I know I'm noob when it comes to syntax, but I'm pretty sure that OL is defined earlier. Do you know what's going on here?</div>

<div></div>Hi Rosco,
<div><br></div>
<div>No, I hadn't thought of that. Any suggestions on how to update the position
of the marker, maybe a loop with a new LonLat?<br><br>
