Map Code

var myMap;
    var myPlacemark;

    var init = function init() {

        center: [55.782889, 37.725994],
        zoom: 18,
        controls: []
      });
      myMap.behaviors.disable('scrollZoom');
      var myPlacemark = new ymaps.Placemark([55.782636, 37.726417], {}, {
        iconLayout: 'default#image',
    
      });
      myMap.geoObjects.add(myPlacemark);

Something like is required

$('.contacts .tab').on('click',function(){
   

    // Contacts Lat and Log

    
    lat = 55.782889;
    lng = 37.725994;
    myPlacemark.setCoordinates([ lat, lng]); // Это пример, он не работает



  })
