Error #1009 Null Object Reference

[inbound spot thoughts]

The information can be found in the image below please let me know if you can't read it. The reference to "Awsome Game Folder" in the output screen can be attributed to the following Box2D zipped file downloaded from the following address if you want to follow along. its http://sourceforge.net/projects/bpx2dflash/  Line # 21 on this image should be world.clearforces();

Additionally the same problem occurs with this code which is the next code in the process

world is null in your first code snippet.

that's because you defined two different variables to have the name world.  one, that's global to your Main class and one that's local to your Main constructor.

that's an error.  you certainly wouldn't want two same named variables referencing different objects.

Sir, So how do I fix it?  I am copying this straight from a text book so I don't get why its wrong.
