timw@acponline.org: Ken, Thank you for the reply. I have just tried this, but I am unclear whether or not it worked. I replaced the line as you suggested, and the warning does not appear. However, when I view the resulting source there is no reference at all to the syntaxhighlighter.css. It looks as if the entire <link ... /> reference is not even there... Yes, I have cleared my cache/browsing history/Ctrl+F5 with same result. Is this an expected behavior? How can I verify that the CSS file is being properly included/referenced? -Tim Hi timw@acponline.org, You can try the "Syntax Highlighter Code" function to inster some code. If the stylesheet is applied, the cdoe will like beow else will like Regards, ken
