Hi,

There was an error on geomap script. It use the getElementsByClassName method, which is no more supported in recent navigators. So I uses this script found on about.com

  /**
   * Implement the getElementsByClassName
   */     
  document.getElementsByClassName = function(cl) {
    var retnode = [];
    var myclass = new RegExp('\\b'+cl+'\\b');
    var elem = this.getElementsByTagName('*');
    for (var i = 0; i < elem.length; i++) {
      var classes = elem[i].className;
      if (myclass.test(classes)) {
        retnode.push(elem[i]);
      }
    }
    return retnode;
  };

You just have to insert this code in the script.
