re: Please Help due in 45 min

This isn't a chat room, so you can't possibly expect an answer within 45 minutes. Also, we don't give out full solutions, we merely guide you to solving your own problems. We'd love to go through any specific issues you have if you can show us what you're attempted in order to solve them.

Additionally, please don't post two threads on one topic. It doesn't get you an answer any faster - if anything, it slows the response down, because people don't know what has been posted in the second topic, and they might repeat information. So basically keep it to one thread per topic.
