Lorentz attractor code not working properly. Issue with peasy

The code works but not the way it should. I first followed Daniel Shiffman's youtube and code along with him. Second time I just copied and paste the code from codingchallenge website still same. I have attached screen shot of the console and the code for your reference. Thanks.

Oh I forgot, I have imported the peasycam library into my sketch and in my processing compiler.Thanks again.
