"I wrote a program. It doesn't work. Please help me fix it." So many
questions.

With so little information, any answer might be reasonable--like
"there's an elephant in your plumbing--please try removing it.".
"Your children are plotting against you--that's probably what's

We're happy to help, BUT, we cannot provide help with a question that is
so vague as to be of NO HELP TO THE HELPERS.
