I am assisting a friend with her website. Iuse NVU to edit and Core to transfer files. She has a one or two liner change, once or twice a week. The first time I edited the page and transered the change showed up on the site. Since that time, the change will not show up. I just attempted it again and got the aboe log. I really need help urgently. Thanks. Shartree

Have any ideas why a link won't work on the index page on aol, but it will on IE and Mozilla?
