Check the source!

I am lost.  I "viewed the source". I found Zach's message.  Yes, I know I need to get to level 2 :)  I entered random words from that page (have no clue which one is the source)  but go nowhere.  ex. z-toc.com/?????.htm  Would that be the correct way to enter it?  Thanks

 The correct way to go to the next page would be to take the info he gives you in the source....and change where it says level1.htm on the web address to the next one.
