and part creates error:

function getcurrentposition_success(position) {

        if (counter > 0)             (var = 0; < markers.length; i++) {                 markers[i].setmap(null);                 markers = [];                 counter = 0;             }          co = position.coords; // set short variable conviniece         var pos = new google.maps.latlng(co.latitude, co.longitude);         var marker1 = {//the radius marker             strokecolor: '#0000ff',             strokeopacity: 0.5,             strokeweight: 2,             fillcolor: '#0000ff',             fillopacity: 0.35,             map: map,             center: pos,             radius: 5,             title: 'you here',         };         circleradius = new google.maps.circle(marker1);         markers.push(marker1);         counter++;         map.setcenter(pos); // center map around position of user          request = {             nodenumber: num,//destnum             posx: co.latitude,             posy: co.longitude         }         getdistance(request, getdistancesuccesscb, getdistanceerrorcb);      }

you setting marker1 javascript object , not google maps marker object, , doesnt have setmap() method google markers do. set maps marker object need use 

var marker1 = new google.maps.marker({
