the tree Posted July 26, 2009 Share Posted July 26, 2009 Sure enough we're not going to give you the final answer just like that, but giving the rest isn't much better until you demonstrate that you've done enough of the work yourself to learn something.

Bignose Posted July 27, 2009 Share Posted July 27, 2009 Thank you DJBruce. The Tree:), I already have the answer, but I don't know how that arrived to it so I want to open discuss to provide it step-by-step Sweetness, the point is that the forum members aren't just going to provide it for you. We encourage you to do your own work. Why don't you post what steps you do know and we'll comment on that. Or, at least post your ideas about what the steps may or may not be and we'll help talk through that. What we won't do is spoon feed you answers.
