 * Hi all,
 * I’m trying to set a global variable in header.php that is tested in single.php
   and category.php.
 * Below is the code I’m using. This works on single pages, but it does _not_ work
   on category pages.
 * What am I missing?
 * this is in my header.php
 *     ```
       if (in_category( array('cat1','cat2','cat3')) || is_category( array('cat1','cat2','cat3')) || is_page('MyPage')) {
       global $subnav;
       $subnav = "foo";
       }
       ```
   
 * this is in both single.php and category.php
 *     ```
       get_header();
       if ($subnav == "foo") {
       include(something);
       }
       ```

 * Forget it. I figured out a workaround by moving the conditionals and setting 
   of the global variable into functions.php.
 * It also tripped me up that is_archive() returns TRUE for category pages as well.
