[Tutor] A better way to do it.

[Jacob S.]

Okay, here's the code.

I am completely open to suggestions as this is my first dabbling in Tk.
Please look over it when you have time.

I have a couple of questions.
1) How do I change the title of the window?
2) Why does a window pop up saying something like error, the memory could
not be "read". I'm running
Windows XP, the script window disappears, and everything, just this message
pops up.
