Importing integer from config file

I am working on a plugin just for experience's sake that is like a world guard plugin. All I am struggling with is when you type '/mark' it saves to a config file, the location and the radius you want, It's working perfectly until the radius part. There are no errors when saved and compiled but in the game it doesn't let me place stuff within the radius I want. It doesn't let me place stuff anywhere.

Code:java

package me.Jordan.Arena;

import org.bukkit.Location;
import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;

import org.bukkit.event.block.BlockPlaceEvent;

public class PlayerListener implements Listener{
 
    public Main plugin;
 
    public static Material[] banList = {Material.TNT};
 
    public PlayerListener(Main instance){
        plugin = instance;
    }
 
    //int r = 10;
    @EventHandler
    public void onDamage(EntityDamageByEntityEvent event){
 
        Player player = (Player) event.getEntity();
 
        if (event.getEntity() instanceof Player && event.getDamager() instanceof Player){
            int r = plugin.getConfig().getInt("radius.x");
            int x = plugin.getConfig().getInt("locations.1.x");
            int y = plugin.getConfig().getInt("locations.1.y");
            int z = plugin.getConfig().getInt("locations.1.z");
            Location loc = new Location(player.getWorld(), x, y, z);
            if(player.getLocation().distance(loc) <= r){
                event.setCancelled(false);
                player.sendMessage("debug message:)");
 
            }else{
