@Shammyh comments is just to remind that in this very active forum many topics get quite a bit of attention and response very quickly so it can become frustrating when the question being asked has been asked and answered very very well in another thread some time ago (or before) that could be found through simple searching...
What I find to be most helpful is when someone at least offers clarification in their original posting that they've searched and found and read many threads that might relate (when they exist) but aren't specifically what YOU are trying to understand.
