I dislike reviving threads, but as this one is linked from GoZelda's signature, I felt it necessary to point this out:

In his 'tutorial', he is using => instead of >=. This is a bad thing to do, as it's wrong. The engine's too forgiving of bad code.

So, don't use =>. Use >=. It's pronounced "Greater than or equal to," surprisingly exactly like you learned how to pronounce it in a basic algebra (or even basic math) class!
