 * nope. writes nothing..
 * everything else is fine. i just need the parent category. and best outside any
   loop.
 * `echo(get_category_parents($cat, TRUE, ' &raquo; '));`
 * writes for example
    category >> subcat post subcat post category >> subcategory

 * no, that is not the problem.:)
 * the problem is that the function :
    `echo "<h1>". $cat->name . "</h1>";` writes
   2 categories. one at the beginning – which is good and one at the end (which 
   is a subcategory in category-style) .
 * i think the foreach function is placed wrong. hope u know what i mean.
    thx anyway

 * On the left site you see the navigation structure
 * Title current category
    -title subcategory 1 posts within -title subcategory 
   2 posts within
 * and this is what i want to see on my single.php
 * thanks
