Answer to your situation
Looking at the comments, I went and saw the question (Initially I assumed the answer was literally "I don't know"). It sort of is valid, it provides some constructive material.
Whenever there is a question, not asked by you, which doesn't have quite the answers you want, bounty it and explain what you're looking for in the bounty reason box.
