1) The links to the results page in the menu are not passing the propper query string variables.
In the origianl version of the CSSMenuWriter/cssmw_home/menu.php the links are created on line 69 using the following code:
<li><a href="<?php echo($assumedRoot); ?>Products_Results.php?Search=true&CategoryID=<?php echo $row_menuwriter_productcategories["CategoryID"]; ?>"><?php echo $row_menuwriter_productcategories["CategoryName"]; ?></a></li>
2) make sure to check the Available Online option. If this option is not checked, the items will show that message.
