I made the changes you suggested and it works perfectly. There is no 
need to set "val" to an initial value now that I am writing to the 
correct data type. I can feel better about my code.

Now I can start working on a simple character class to test field 
scrolling and collision detection. I'm really digging OOP at this point. 
My global variables are few and I can load several fields at once. I 
might even have a chance at finishing a game.

Your input has been very helpful! I don't know why I didn't think to 
print values to the console for debugging before, it's so useful :) Now 
I will consider my data types and memory usage more carefully. Thanks 
Darren!

People should know by now not to use IE =P

P.S. I'm jealous. You live near some of the best mineral hunting grounds 
in the U.S. ;)
