Integer is returning 0 when a new player joins the array

Hi, the info that you posted to me works but when a new player joins the hits, every player that have damaged that player returns 0

I get how many times you hit the player and it dosen't give me any errors

Code:java

 
public static Map<UUID, HashMap<UUID, Integer>> cashSplit = new HashMap<UUID, HashMap<UUID, Integer>>(); //Saving the damaged player and how many times a player hitted the damaged player
 
@EventHandler
public void onPlayerDeath(PlayerDeathEvent e){
if((e.getEntity() instanceof Player) && (e.getEntity().getKiller() instanceof Player)){
 
for(Entry<UUID, HashMap<UUID, Integer>> cS : cashSplit.entrySet()){//Looping through data in the hashmap
 
Integer total = 0;
Integer maxPoints = 40; //<--- Max points for each kill
 
for(Entry<UUID, Integer> c : cashSplit.get(cS.getKey()).entrySet()){total = (total+c.getValue());}
 
 
for(Entry<UUID, Integer> c : cashSplit.get(cS.getKey()).entrySet()){//<--- When 2 players are in this hashmap it returns 0
 
int cash = (maxPoints * (c.getValue()/total)); //<--- Returns 0 all the time when a new player joins the hashmap
 
Player p = (Player)Bukkit.getPlayer(c.getKey());
if(p != null){
p.sendMessage("You gained "+cash+ " credits");
}
 
 
Bukkit.broadcastMessage("Player: "+Bukkit.getPlayer(c.getKey()).getName()+" | Clicks: "+c.getValue()); //<--- Works, Tells me the playername and how many times he hit the dead player
}
}
}
}
