Eric : my post was in response to steves post just above and its contained quote. I agree that the homework posts are to be handeled with pointers, as are the thoughtless posts that "read that fine manual" or "search (your topic)" would have answered but "how to make a potential divider" may just indicate as I pointed out that the poster has not had the basics yet for whatever reason and thus should be pointed not roasted however gently. regards Terry
