We are not here 24/7 for you. It's not our fault your logic, deduction is equal to 0.
Dont you fcking see you are under L2JModSettings and not under npcs? That's why you have an error. Open your eyes and use your brain.
Its like, you have a ready good proper method, lines and you should copy paste them, yet you do something other and you wonder why you have an error. God.
And why there is a bracket after that line? You are facking things up by your own stupidity sorry to say that. Everything is correct, you add your 1 line code and you break everything...
You should think what you are doing and think why things are not working, why it show error rather than spamming with silly mistakes. I see that you are not learning after all this time and you can't think logically.
