Hi, I'm pretty new to CSS but less new to PHP. I've simply built a HTML page using a CSS (one of the dreamweaver MX samples!) and it works fine when I call it direct but not when I call it using an include statement inside PHP5. I've added the path to the CSS files inside the PHP but this does not seem to do the trick... Is there anything else I shoudl know or try? Any help much appreciated! Thanks, Darren.
