Scoreboard Below-Name Help

Hey guys! I've been working on a private plugin for my server, but have run into and issue with scoreboards. I require it to show a sidebar to the player showing how many "Coinz" (vault) it has. I also need it to display the players coinz below the nametag too. When I display the below nametag, it shows 0 instead of the actual amount of coinz the have.

Here is my code:

Code:

// Manager is the scoreboard manager in onEnable()
 
@EventHandler
public void Playerjoin(PlayerJoinEvent e) {
Scoreboard board = manager.getNewScoreboard();
Objective o = board.registerNewObjective(e.getPlayer().getName(), "dummy");
o.setDisplayName(e.getPlayer().getDisplayName());
o.setDisplaySlot(DisplaySlot.SIDEBAR);
o.getScore(getServer().getOfflinePlayer("Coinz:")).setScore((int)Math.round(econ.getBalance(e.getPlayer().getName())));
 
Objective oo = board.registerNewObjective(e.getPlayer().getName()+"b", "dummy");
oo.setDisplayName("Coinz");
oo.setDisplaySlot(DisplaySlot.BELOW_NAME);
oo.getScore(e.getPlayer()).setScore((int)Math.round(econ.getBalance(e.getPlayer().getName())));
 
e.getPlayer().setScoreboard(board);
}

 

Old post I know, but as far as Im aware you can only have one scoreboard per player per instance
