Thank you. I don't think stubbornness should really be a problem. There are far worse things than being stubborn. Unfortunately, there is no "frying pan" smily on this site, so I don't have a humorous way to hit you over the head. [img=http://sci.rutgers.edu/forum/images/smilies/fryingpan.gif] Dere it is! We were talking about something before I went mad, but I'm afraid of the previous page now. You wanna see if you can find where we got stuck?
