Help!

I figured out the problem. I wasn't distinguishing the snippets from the listings. I wanted to run listing 6-2 and was instead running snippet 6-2. Running listing 6-2 ran just fine. I also now see why snippet 6-2 failed ... it was supposed to fail because it was trying out watermark which your text indicated should not be used.

I didn't see the snippets mentioned in the text. Is that just extra test cases you created to supplement the text?
