This would throw off all of your stack variables by two bytes each.
Output may be non-zero but I doubt it is correct.
Good Luck...

ha....it sickens me that this was actually the problem. This was the THIRD time I have been screwed by those printf's in C(used to java, C++). Thank You. That fixed the problem, but I'm curious as to how this works. Why does it throw off the stack variables by two bytes each?(Not that I know much about the "stack" anyways
) and how did you know this? Could you point me to a paper or something that explains how some of these "inner workings" work?
EDIT: I knew it expected ints and I forgot that I changed measurement to a long, but I still wouldn't have expected that one mistake to mess up the rest of the function.
