It is considered good form to search the forums before posting a question since often someone else has already asked and answered your question. In this case, I found Kelly Hutchins answered this question just a few months ago:
if you find it necessary to post a new thread, its also considered good form to supply a link if you have cross posted somewhere else (like your identical thread in GIS SE here.)
