Once the query task has been completed I am attempting to get the map to focus to a particular area which is at the 0 item in the parnums array. However that map appears to be focusing other elements in that array (I would say about 1 in 5 times give or take) and I am not sure why. <link href="http://serverapi.arcgisonline.com/jsapi/arcgis/2.5/js/dojo/dijit/themes/claro/claro.css" rel="stylesheet" type="text/css" >
