Plugin Help Changing a sign line with a command.

I need the sign that i'm looking at to change when i run a certain command. This is what I have so far...

Code:

if (cmd.getName().equalsIgnoreCase("ft")) {
            if (!(p.hasPermission("ft.use"))) {
                p.sendMessage(ChatColor.RED + "You do not have permission.");
                return true;
            } else {
                if (args.length == 0) {
                    p.sendMessage(ChatColor.RED + "Usage: /ft <name> <1/2/3/4>");
                    return true;
                } else if (args.length == 2) {
                    String name = args[0];
                    String id = args[1];
                    Sign sign = (Sign) p.getTargetBlock(null, 10).getState();
                    if (args[1].equalsIgnoreCase("1")) {
                        if (getConfig().get("FastTravel." + args[0] + "." + 1) != null) {
                            p.sendMessage(ChatColor.RED + args[0] + " 1 already exists please use another ID.");
                            return true;       
                        }else {
                            if(getConfig().get("FastTravel.Price") != null){
                            sign.setLine(0, "[FastTravel]");
                            sign.setLine(1, name + " 1");
                            sign.setLine(3, (String) getConfig().get("FastTravel.Price"));
                            p.sendMessage(ChatColor.GREEN + "You set the FastTravel sign '" + name + " 1'.");
                            return true;
                            }else {
                                p.sendMessage(ChatColor.RED + "The price for FastTravel has not been set.");
                                p.sendMessage(ChatColor.RED + "Please set the price by using /setprice <price>");
                                return true;
                            }
                        }
                    }
                }
            }

The rest of it works apart from the sign changing... Is there something that i have done wrong?
Please help.

Thanks

Matty.

An example, if someone was to run the command '/ft Test 1', The sign that they were looking at would change to this
Line 1 - [FastTravel]
Line2 - Test 1

Line 4 - Price

@HCMatt
Try adding sign.update(); after setting all the lines...
EDIT: why did you use equalsIgnoreCase in line 13?
no need for "else" when doing return;
