Variable isnt displaying in console log outside of function in angular

I am trying to use a variable in another function to create a map marker using angular.
i got the data to be stored in the function and display on the console within one function however when using the data in another function it does not work:

this.getparamformid = this.route.snapshot.paramMap.get('facviewid');
    this.daformfacservice
      .getOneDAFacForm(this.getparamformid)
      .subscribe((daFormFac: DAFormFac) => {
        this.daformfacs = daFormFac;
        console.log(daFormFac, 'response of form');
        this.latitude =  daFormFac['latitude'];
        this.longitude = daFormFac['longitude'];

        console.log(this.latitude, this.longitude, "cords")
      });
    let map = L.map('map').setView([10.536421, -61.311951], 8);
    L.tileLayer(
      'https://api.mapbox.com/styles/v1/{id}/tiles/{z}/{x}/{y}?access_token={accessToken}',
      {
        attribution:
          'Map data &copy; <a href="https://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors, Imagery © <a href="https://www.mapbox.com/">Mapbox</a>',
        maxZoom: 18,
        id: 'mapbox/streets-v11',
        tileSize: 512,
        zoomOffset: -1,
        accessToken:
          'accesstoken',
      }
    ).addTo(map);
    var marker = L.marker([this.latitude, this.longitude]).addTo(map);
    console.log(this.latitude, this.longitude, "in marker")
  }

This function gets the data entry and stored 2 variables latitude and longitude:

this.daformfacservice
          .getOneDAFacForm(this.getparamformid)
          .subscribe((daFormFac: DAFormFac) => {
            this.daformfacs = daFormFac;
            console.log(daFormFac, 'response of form');
            this.latitude =  daFormFac['latitude'];
            this.longitude = daFormFac['longitude'];
    
            console.log(this.latitude, this.longitude, "cords")
          });

and it results in

however when trying to access the data outside the function the console is blank.

var marker = L.marker([this.latitude, this.longitude]).addTo(map);
console.log(this.latitude, this.longitude, "in marker")

It does not display and is not accessible. what should i do?
