Error in eventHandler - public function init()

Hey! This thingy

PHP:

$this->api->addHandler("player.move", array($this, "eventHandler"), 100);

gives me the following error:

Code:

2013-11-22 §b15:31:54§r [ERROR] A level 4096 error happened: "Argument 2 passed to PocketMinecraftServer::addHandler() must be callable, array given, called in C:\Users\Niklas_2\Documents\Programmierung\PocketMine\TestServer\Tutorial Server\PocketMine-MP\src\API\ServerAPI.php on line 315 and defined" in "C:\Users\Niklas_2\Documents\Programmierung\PocketMine\TestServer\Tutorial Server\PocketMine-MP\src\PocketMinecraftServer.php" at line 269

whats the problem?
I can't see it.

Thanks!

make sure that you got a function "eventHandler" and that it's public

Sure...

PHP:

public function eventHanlder($data, $event)

You spelled the function wrong

Thanks. Sorry for my stupid question!
It is really hard to code when you are severely visually impaired...
