Uh, well I guess that should have seemed obvious to me, huh? You know I had
a do-while loop in there at one point and was getting another error (for
reasons I won't now go into).... Well, suffice it to see I stopped thinking
when in my casting about I put the condition at the top and the other error
went away.
Thanks for pointing out that the emperor has no clothes!
