I have made certain that the name is correct and tried a few other ideas as well. Heck, I even changed the tab order. Still, the error persists. Obviously, I am making a basic error with this class. I'll bump it into my todo list and come back and fight it when I've completed the rest of the project. In the mean time, if you think of anything for me to try, I shall gratefully receive your missives.

Cheers
