GetItem Problem

[ThunderStefan]

Hi ole,
first I would like to thank you for the great work.
I've been trying to get the admintoolkit to work completely for a long time.
Unfortunately I still have the problem to get the feature getitem to work.
I always get this error message:

14:53:05 "[ADMINTOOLKIT] Calling getitem from player Thunder"
14:53:05 Error in expression < };
};
case "getitem": {
if (_params != "") then { _player addItem _params; }>
14:53:05 Error position: <!= "") then { _player addItem _params; }>
14:53:05 Error !=: Type Array, expected Number,Bool,String,Namespace,Not a Number,Object,Side,Group,Text,Config entry,Display (dialog),Control,Network Object,Team member,Task,Diary record,Location
14:53:05 File admintoolkit_server\code\AdminToolkit_network_receiveRequest.sqf..., line 189
14:53:05 Error in expression < };
};

Please can you help me and fix the issue?
Or can you tell me what i make wrong?

Thank you in advance :-)
