Thanks. I thought about that too, but then I checked some of my other profiles that were showing the sources. and discovered I had removed the references code (don't know why) but the sources were still showing up. Other profiles had the references code and the sources showed up. So whether the references code was there or not, didn't seem to be connected as to why the sources were not showing up on some of my profiles. It has to be because of the privacy issue.
I had the privacy issue set to show the biography, which it did, but again it did not show the sources even to me in private mode. They only showed up when I was in edit mode. Just bewildering!
