Solved Comparing Sign Values?

Hello I am trying to make a script where if you right click a sign then it toggles the second line(1) from saying 'true' and 'false'.
Code:

Code:

public void onClick(PlayerInteractEvent){
  if(e.getAction == Action.RIGHT_CLICK_BLOCK){
    if(e.getTargetBlock(null, 10).getType().equals(Material.WALL_SIGN)){
                    Sign s = (Sign)e.getPlayer().getTargetBlock(null, 10).getState();
                    if(s.getLine(1).equalsIgnoreCase("true")){
                        this.value = false;
                        s.setLine(1, "false");
                        s.update();
                    }else{
                        this.value = true;
                        s.setLine(1, "true");
                        s.update();
                        Bukkit.getLogger().info(s.getLine(1));
                    }
    }
  }
}

EDIT: The problem is that It only changes the sign to say 'true' and dosent change if I keep clicking it...

 

@B3N909 This code has so many errors, you can't compile it. Is this pseudo code?
Why do you use this player.getTargetBlock.... and not event.getClickedBlock()? I wrote my own little method, worked perfectly fine using the getClickedBlock...

 

@I Al Istannen It appears that I cannot get a WALL_SIGN if I use PlayerInteractEvent.getClickedBlock() on a Action.RIGHT_CLICK_BLOCK?

 

@B3N909 I'm sorry, but I don't understand the question.

 

@I Al Istannen If I right click a sign then e.getClickedBlock() does not return anything... Can I see a snippet of your code?

Thread Solved.

@B3N909 You did it? Just be careful as the event.getClickedBlock() can return null.
