John, sorry for not being helpful. But I think that this kind of posts (this
is my code, why it doesn't work?) will not help you to find the problem. My
suggestion is, try to debug your code, and if you have a more specific
question, post it and somebody for sure will give you an answer. Otherwise,
everybody will just overlook your post. The most of developers are too lazy
to find what exactly is not right with your code.
Alex.
