How to load a notification panel when user comes at particular gps location

using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.UI; using UnityEngine.Android; using UnityEngine.Serialization;

public class dropplacer : MonoBehaviour

{ public Text gpsOut; public GameObject locationpanel; public GameObject notificationpanel; public float Longitude; public float Latitude; public bool isUpdating; private void Update() { if (!isUpdating) { StartCoroutine(GetLocation()); isUpdating = !isUpdating; } }

 IEnumerator GetLocation()
 {
     if (!Permission.HasUserAuthorizedPermission(Permission.FineLocation))
     {
         Permission.RequestUserPermission(Permission.FineLocation);
         Permission.RequestUserPermission(Permission.CoarseLocation);
     }
     // First, check if user has location service enabled
     if (!Input.location.isEnabledByUser)
         yield return new WaitForSeconds(10);

     // Start service before querying location
     Input.location.Start();

     // Wait until service initializes
     int maxWait = 10;
     while (Input.location.status == LocationServiceStatus.Initializing && maxWait > 0)
     {
         yield return new WaitForSeconds(1);
         maxWait--;
     }

     // Service didn't initialize in 20 seconds;

     if(maxWait < 1)
     {
         gpsOut.text = "Timed out";
          print("Timed out");
         yield break;
     }

     // Connection has failed
     if (Input.location.status == LocationServiceStatus.Failed)
     {
         gpsOut.text = "Unable to determine device location";
         print("Unable to determine device location");
         yield break;
     }
     else
     {

         gpsOut.text = "Location: " + Input.location.lastData.latitude + " " + Input.location.lastData.longitude + " " + Input.location.lastData.altitude + 100f + " " + Input.location.lastData.horizontalAccuracy + " " + Input.location.lastData.timestamp;
         // Access granted and location value could be retrieved
         print("Location: " + Input.location.lastData.latitude + " " + Input.location.lastData.longitude + " " + Input.location.lastData.altitude + " " + Input.location.lastData.horizontalAccuracy + " " + Input.location.lastData.timestamp);

         if ((Latitude == Input.location.lastData.latitude)&&(Longitude == Input.location.lastData.longitude))
         {
             locationpanel.SetActive(true);
             
         }
        else
         {
           
             notificationpanel.SetActive(true);
         }

     }

     // Stop service if there is no need to query location updates continuously
     isUpdating = !isUpdating;
     Input.location.Stop();
 }

} This is the code used but it wont work.it has no errors
