maps not working?

Hi:

Thanks for the great work on this module. I installed the latest development release, but haven't been able to get the map functionality to work properly. I've gotten a google maps api code via the link provided and added it my listing settings. However, when I create a listing and input address, etc., I can see the collapsible fieldset but no map is displayed. The AJAX version acts the same.... tries to load but ends up blank w/ no error thrown. Checking my source, it looks like the only thing lacking from google's code example to mine is the < body onload="load()" onunload="GUnload()" >, which isn't in my source code. Adding it manually to page.tpl.php didn't solve the problem. The javascript looks roughly the same, though.

Here's the whittled-down source code I end up with for a listing's page display:

< script src="http://maps.google.com/maps?file=api&amp;v=2&amp;key=ABQIAAAAMxPEff_I79pUv4exgMDioBSxQ7j6HxsABgzrKWtHwLbBi0XJpBRvlXODsi-Oes-Eo7XravqOoYwR9A" type="text/javascript" charset="utf-8"></ script>

< script type="text/javascript">$(document).ready(function(){
      		if (GBrowserIsCompatible()) {
        		var map = new GMap2(document.getElementById("map_canvas"));
        		var center = new GLatLng(, );
        		map.setCenter(center, 12);
				map.addControl(new GLargeMapControl());
map.addControl(new GMapTypeControl());
				var marker = new GMarker(center);
				map.addOverlay(marker);
      		}	
		})< /script>

	< fieldset class='collapsible'>
		< legend>Map< /legend>
		< div class="form-item">
			< center>
    		< div id="map_canvas" style="width: 400px; height: 300px">< /div>< /center>< /div>< /fieldset>

Any assistance would be appreciated. Thanks.
