есть две функции.

function calcRoute() {
  var start = document.getElementById('start').value;
  
  var end = document.getElementById('end').value;
  
  

  var request = {
      origin: start,
      destination: end,
     
     
      travelMode: google.maps.TravelMode.DRIVING
  };
  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
      var route = response.routes[0];
      var summaryPanel = document.getElementById('directions_panel');
      var f;
      var f1;
      summaryPanel.innerHTML = '';
      var a1;
      var a;

      // For each route, display summary information.
      for (var i = 0; i < route.legs.length; i++) {
        f=(route.legs[i].end_location.lat()-route.legs[i].start_location.lat())/10 ;
        f1=(route.legs[i].end_location.lng()-route.legs[i].start_location.lng())/10;

                        summaryPanel.innerHTML +=' Координаты начала '+ route.legs[i].start_location + ' среднее ';
                        summaryPanel.innerHTML += f  + '<br>';
                        summaryPanel.innerHTML += f1  + '<br>';
                        summaryPanel.innerHTML += 'Время:'+route.legs[i].duration.text + '<br><br>';
                        
                      
var markers = [];
for(var k=1; k<=9; ++k)
  markers[k-1] = new google.maps.Marker({
    position: new google.maps.LatLng(route.legs[i].start_location.lat()+f*k, route.legs[i].start_location.lng()+f1*k),
    icon: destinationIcon,
    map: map
  });




                a=route.legs[i].start_location.lat()+f;
                        a1=route.legs[i].start_location.lng()+f1;
                                

                    
      


      }  
    }
  });

}


function calcRoute1() {

  

  var start = document.getElementById('start').value;
  var end1 = new google.maps.LatLng(calcRoute(a), calcRoute(a1));


Uncaught ReferenceError: a is not defined

  
  


  var request1 = {
      origin: start,
      destination: end1,
     

     
      travelMode: google.maps.TravelMode.DRIVING
  };

  directionsService1.route(request1, function(response1, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response1);
      var route1 = response1.routes[0];
      var summaryPanel1 = document.getElementById('directions_panel1');
     

      summaryPanel1.innerHTML = '';
      // For each route, display summary information.
      for (var i = 0; i < route.legs.length; i++) {
       

                        summaryPanel1.innerHTML += 'Время:'+route.legs[i].duration.text + '<br><br>';
                        



  


});



                       

                    
      


      }  
    }
  });

}

нужно передать из функции calcRoute() в функцию calcRoute1() переменную a.
