Tabbing really comes in handy to know if you're missing }'s or not. You've got sender.sendMessage tabbed and then below that everything is missing a tab, you are still missing a } at the end of your file. If using eclipse CTRL + A then CTRL + SHIFT + F will format it and you will see where you're missing it. I don't know the keybinds for any other IDE
I would suggest learning Java and looking around before asking about something as simple as that. Based on what error you're getting, you're using Eclipse, and Eclipse tells you what to do.
Okey, look at my 3th line! Maby that will help. if (!(sender instanceof Player)) { sender.sendMessage(ChatColor.RED + "The console can not use Chatzy"); This thing >>>>> } <<<<< Okey?
BearstudioMC You are still missing multiple '}'s. At least two. Take a close look, and find out where. In most IDE's (even Notepad ++), if you put the cursor next to a '{', it will highlight both it, and its matching closing bracket.
