Optional Sidebars / Lines Separating Widgets

Good day - I have 2 questions. 1 - I have tried to activate the Optional Sidebars. Unfortunately, when I drag/drop the widgets in the areas of Optional Sidebar One, Two or Three, the widget is not displayed. They work in the Main Sidebar only. I have also tried the same in the Optional Post Sidebar with no success. Can you help me resolve? 2 - I would like to insert a thin horizontal line between each of the widgets in the Sidebar (main or other) to give better visual separation. Can you suggest code that would accomplish this? www.ChipBunnell.com/blog Thank you for your help! chip
