    Hi, Battleaxe!

    If you post the work that you've already done on the problem, it's likely that someone very knowledgeable concerning what you're asking, will come along to help you.

    But, you do need to post the work that you've already done first in order to solve the problem that you're trying to solve.

    Thanks!
