Here's the function it passes a value to if that sheds any light.
function addResult(result) {
//clear any existing graphics
map.graphics.clear();
//add selected geocode result to map and zoom
var infoTemplate = new esri.InfoTemplate("Result", "${*}");
var r = Math.floor(Math.random() * 250);
var g = Math.floor(Math.random() * 100);
var b = Math.floor(Math.random() * 100);
var symbol = new esri.symbol.SimpleMarkerSymbol(esri.symbol.SimpleMarkerSymbol.STYLE_CIRCLE, 10, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([r, g, b, 0.5]), 5), new dojo.Color([r, g, b, 0.9]));
var wmloc = esri.geometry.geographicToWebMercator(result.location);
var attr = {
"Address" : result.address
};
var graphic = new esri.Graphic(wmloc, symbol);
map.graphics.add(graphic);
var ptAttr = result.attributes;
map.centerAndZoom(wmloc,15);
//close the dialog
$('.ui-dialog').dialog('close');
}
