i inserted this tag <!--#include virtual="lw_code.php"--> (i have no idea what it means, the instructions says to add this) and i get teh error message at the top of my page: the php was given to me too.
Well, if that line is in your HTML, it should be ignored as it's between comment tags. If it's in PHP the html comment tags should probably be removed...
you need to have the absolute FULL pathname to the file and not the relative one.. eg <!--#include virtual="/root/subdirectory/phpfile.phpl" -->
