Re: Why can't the second hand go to twelve?

Sorry, what you need is someone with a lot of free time to help you out.

First, code tags!
Second, COMMENTS! Your code is all crammed together with no comments. One has to understand fully what your code is doing before they can truly help you!

Once you fix that, and make it more clear exactly what your problem is, then help can be provided!
