Hey, George,

Well, as it turns out, just a little bit of JavaScript (and CSS) was needed to get your snippet to work: you needed to call the "initMap" function so the map initialization would occur, along with the radio button logic. Just add "google.maps.event.addDomListener(window, 'load', initMap);" right before the closing </script> tag. 

Then you'll have everything initialized, but the map container with 0 pixels of height. I'd change the #map class to something like this:

#map {
  min-height: 500px;
  width: 100%;
}

Then you'll have your example working! But if you're wondering how to get it working with a "Map" block from the component itself, then check out the attached OML (which also includes your code with my changes, along with the one you saw above).

Is this what you were looking for?

Best regards,

Carlos Simões
