# Problem with separator

 * I’m using the following in my query to display the child categories
 *     ```
       <?php
       foreach((get_the_category()) as $childcat) {
       if (cat_is_ancestor_of(1, $childcat)) {
       echo $sep,'<a href="'.get_category_link($childcat->cat_ID).'">',$childcat->cat_name,'</a>';
       $sep = ' / ';
       }}
       ?>
       ```
   
 * So this is then displaying as follows:
 * Category a / Category b / Category c
 * The problem is when there’s more than one post on the page the next lot show 
   as
 * / Category a / Category b / Category c
 * i.e. it’s just continuing to add the forward slash and not simply starting the
   query again.
 * Basically I need it so the separator does not show at the beginning or end of
   the category list.
 * Any help would be greatly appreciated.

 * there is a comma after `$sep` which might break the code – should be a dot;
 * try:
 *     ```
       <?php
       foreach((get_the_category()) as $childcat) {
       if (cat_is_ancestor_of(1, $childcat)) {
       echo $sep.'<a href="'.get_category_link($childcat->cat_ID).'">',$childcat->cat_name,'</a>';
       $sep = ' / ';
       }}
       ?>
       ```

 * Thanks for that – I’ve changed the comma to a full stop but it hasn’t had any
   effect to the original issue.

 * ok, i get it 😉
 * before the foreach, you need to reset the separator to an epmty space:
 * `$sep = '';`
