Below is my code, and basically what I'm trying to do is calculate distance from lat/lons in the database to my current location..

i=0;
                while (rows.isValidRow()) {
                    //var d='';
                    //d=distance(mylatitude,mylongitude,rows.fieldByName('lat'),rows.fieldByName('lon'));
                    //d=distance_plane(mylatitude,mylongitude,rows.fieldByName('lat'),rows.fieldByName('lon'),"N");

                //var url='http://maps.googleapis.com/maps/api/directions/json?origin=30.5166667,-86.4822222&destination=30.7619444,-86.5705556&sensor=false';

            var url='http://maps.googleapis.com/maps/api/directions/json?origin='+mylatitude+','+mylongitude+'&destination='+rows.fieldByName('lat')+','+rows.fieldByName('lon')+'&sensor=false';

             req = Ti.Network.createHTTPClient(); 
            req.open('GET', url);

            req.setRequestHeader('Content-Type', 'application/json; charset=utf-8');
            req.onreadystate = function(){};
            req.onload = function() 
            { 
                try { 
                    parsedData = JSON.parse(req.responseText);
                    newDistance[i]=parsedData.routes[0].legs[0].distance.text;
                    //newDistance="distance.text " + parsedData.routes[0].legs[0].distance.text;
                    Ti.API.info(newDistance[i]);
                    //Ti.API.info("distance.value " + parsedData.routes[0].legs[0].distance.value);
                    //Ti.API.info(newDistance);

                }  catch(err) { 
                     Ti.API.info('>>>>>>> Error In getToken ' + err ); 
                    //newDistance="Error Calculating";
                } 
            };

            req.send();

                  data.push({
                    id: rows.fieldByName('id'),
                      lat: rows.fieldByName('lat'),
                    lon: rows.fieldByName('lon'),
                    title: rows.fieldByName('caption') + ' - ' + newDistance[i],                
                    info: rows.fieldByName('info'),
                    hasChild: true


                });
                //latarray[i]=rows.fieldByName('lat');
                //lonarray[i]=rows.fieldByName('lon');
                //titlearray[i]=rows.fieldByName('caption');
                //subtitlearray[i]=rows.fieldByName('info');

                i++;
               // newDistance[i]='Calculating...'
                                    rows.next();
                }
                rows.close();

It's the newDistance[i] thats giving me an error. I have it defined as an array elsewhere, along with the parseData, and the req variables.

With the newDistance, if I use it as a regular variable instead of an array, it works, except that all the rows get the last calculated distance. Any ideas what I could do to fix it?
