I am having issue when I try to add a style sheet. I am going into
Site Settings then Change portal site properties and Sharepoint site
creation settings. I am adding a style sheet that was created in
Frontpage. I am using Sharepoint portal server 2003. The error that
I am getting is "Error on Page" in the bottom left corner of IE and
then when I look at the details I get "Line: 21, Char: 1, Error:
Object Expected, Code: 0, url: http://spslab1/default.aspx". I have
since removed the css in the same manner that I added it and still get
the error message on the page.

I hope I provided enough details.
