Hi

I'm trying to hack about with the query tasks to get a YEs/No reply to a simple question - does the point passed to a page fall within our area

I have code like (x & y get defined earlier from URL parameters)

 function checkus() {
 
  queryTask = new esri.tasks.QueryTask("http://<our server>/ArcGIS2/rest/services/eforms2/MapServer/0");
  var point = new esri.geometry.Point(x, y, new esri.SpatialReference({wkid:27700}));
  query = new esri.tasks.Query();
  query.returnGeometry = false;
  query.geometry = point 
  query.outFields = ["admin_name"];
  queryTask.execute(query);
  dojo.connect(queryTask, "onComplete", function (results) {
   if (results.features.length>0) {
    alert("In Our Area");
   }
   else {    
    window.location = "NoUs.asp"
   } 
      }  
    
  );



}


I am trying to insert a variable inside the the bit that looks for the number of records returned, but try as I can, I can't get the variable to be global, as soon as that part finishes, so, it appears does the variable.

I must be doing something totally daft here.

Cheers
