Error :(

I tried making a plugin and got this while enabling this. I tried looking at it but I'm not too sure what it means...

Code:

10:18:08 [SEVERE] Error occurred while enabling VaultTest v1.0 (Is it up to date?)
java.lang.NullPointerException

EDIT: The plugin does everything its supposed to xD it still has this in console, however.

 

Well, you got a null pointer exception at the class vaulttest at line 51 at the event "setupChat".

I think it would help you to read this post: http://forums.bukkit.org/threads/ho...ubleshoot-your-own-plugins-by-yourself.32457/

Here an example code how a null pointer exception can happen:

 

You should post the source here.
