The way you presented your problem makes no sense. What are the instructions? What are you supposed to do?
While we're at it, just what do you mean by "solve problem now"? Is that an order? Well, Yes Sir, General, I'll just get right on that -- NOT. This is a site staffed by VOLUNTEERS who do this work for NO COMPENSATION. You ask for help; you do NOT demand help. Capisce?
