Bukkit

Hi, i'm using this plugin and its works all good except the rewards file, chests are enable but i dont know how to enable furnaces hoppers and chest minecarts Can someone please help me?
What do i need to write in the reward file?

Ignore that post, i've already fixed it, but i need help with the commands, i have a server using this plugin, but i need dev's help, in VikkCraft SurvivalGames They changed the "/sg bounty {player name} {amount}" To "/bounty {player name} {amount}" And i want to change the command too, how can i do it?
