Problema con Javascript en el API de Google Maps

[jorgerock]

Buenas... tengo el iguiente problema con el api de google maps, más especificamente con el Geocoding, ya que lo agrego a mi código y creo el form para la busuqeda de direcciones, pero al darle a buscar, no lo hace solo vuelve a cargar el mismo mapa.

Mi codigo es este:

Código HTML:

 <script type="text/javascript">
    //<![CDATA[

    var iconBlue = new GIcon(); 
    iconBlue.image = 'http://jorgerock.com/mapas/mm_20_blue.png';
    iconBlue.shadow = 'http://jorgerock.com/mapas/mm_20_shadow.png';1
    iconBlue.iconSize = new GSize(12, 20);
    iconBlue.shadowSize = new GSize(22, 20);
    iconBlue.iconAnchor = new GPoint(6, 20);
    iconBlue.infoWindowAnchor = new GPoint(5, 1);

    var iconRed = new GIcon(); 
    iconRed.image = 'http://jorgerock.com/mapas/mm_20_red.png';
    iconRed.shadow = 'http://jorgerock.com/mapas/mm_20_shadow.png';
    iconRed.iconSize = new GSize(12, 20);
    iconRed.shadowSize = new GSize(22, 20);

    customIcons["restaurant"] = iconBlue;
