         $Path[] = $data["Name"];

recursePathLookup($data["SubCategoryID"], $Path);

change to:
return recursePathLookup($data["SubCategoryID"], $Path);

      } else {

         //print_r($Path);

         return $Path;

      }

   }

   print_r(recursePathLookup(2));

Any ideas why when I uncomment the //print_r($Path) inside the function it
prints the value fine, but when I try to return the value and print it
outside the function I get nothing?

Thanks,

Nate
