I have no shame in saying that i have no clue how to read or research this further.  I apologize if this is a simple-minded mistake.  Thanks for any help!

Alright, simple enough.  Thank you for that.  I cant believe i didn't find that, I looked through those forums once before.  Oh well, on to the next project.  Thanks again!
