C# Windows .Net "Random" not behaving properly, any one have any idea?

Hi every one, I am trying to implement a custom class in the additional code area and for some reason it has been giving me errors, after trying to debug the problem I found it was this…

Any thoughts?

thanks to all

Forget it, stupid mistake while translating form Processing to C#, wrong inputs :S

My eyes are playing tricks on me! to much looking into the screen!

sorry for wasting your time!
