# Child Theme functions.php error when trying us pluggable function from parent.

 * [12 years, 7 months ago](https://wordpress.org/support/topic/child-theme-functionsphp-error-when-trying-us-pluggable-function-from-parent/)
 * I’ve read about using the pluggable functions and have tried to implement a simple
   override using one, but it keeps throwing an error. Here is a page that I read
   about doing this using the Twenty Eleven Theme: [. I’m trying to do something similar with the Twenty Thirteen Theme.](http://codex.wordpress.org/User:Adeptris/Twenty_Eleven_Child_Theme_add_pagenavi_and_paginate)
 * I’m simply trying to replace the arrows in the previous and next page links on
   the Twenty Thirteen Theme at the bottom with a small image on my Child-Theme.
   I don’t want to just hide the DIV with CSS as I need that DIV to show my image
   in. Here is the code I modified from the functions.php from Twenty Thirteen (
   I simply removed the 4 instances of the arrows and replaced that with the image
   link).
 *     ```
       <?php
       if ( ! function_exists( 'twentythirteen_paging_nav' ) ) :
       /**
        * Displays navigation to next/previous set of posts when applicable.
        *
        * @since Twenty Thirteen 1.0
        *
        * @return void
        */
       function twentythirteen_paging_nav() {
       	global $wp_query;
   
       	// Don't print empty markup if there's only one page.
       	if ( $wp_query->max_num_pages < 2 )
       		return;
       	?>
       	<nav class="navigation paging-navigation" role="navigation">
       		<h1 class="screen-reader-text"><?php _e( 'Posts navigation', 'twentythirteen' ); ?></h1>
       		<div class="nav-links">
   
       			<?php if ( get_next_posts_link() ) : ?>
       			<div class="nav-previous"><?php next_posts_link( __( '<span class="meta-nav"><img src="/images/ArrowL.png" /></span> Older posts', 'twentythirteen' ) ); ?></div>
       			<?php endif; ?>
   
       			<?php if ( get_previous_posts_link() ) : ?>
       			<div class="nav-next"><?php previous_posts_link( __( 'Newer posts <span class="meta-nav"><img src="/images/ArrowR.png" /></span>', 'twentythirteen' ) ); ?></div>
       			<?php endif; ?>
   
       		</div><!-- .nav-links -->
       	</nav><!-- .navigation -->
       	<?php
       }
       endif;
   
       if ( ! function_exists( 'twentythirteen_post_nav' ) ) :
       /**
        * Displays navigation to next/previous post when applicable.
       *
       * @since Twenty Thirteen 1.0
       *
       * @return void
       */
       function twentythirteen_post_nav() {
       	global $post;
   
       	// Don't print empty markup if there's nowhere to navigate.
       	$previous = ( is_attachment() ) ? get_post( $post->post_parent ) : get_adjacent_post( false, '', true );
       	$next     = get_adjacent_post( false, '', false );
   
       	if ( ! $next && ! $previous )
       		return;
       	?>
       	<nav class="navigation post-navigation" role="navigation">
       		<h1 class="screen-reader-text"><?php _e( 'Post navigation', 'twentythirteen' ); ?></h1>
       		<div class="nav-links">
   
       			<?php previous_post_link( '%link', _x( '<span class="meta-nav"><img src="/images/ArrowL.png" /></span> %title', 'Previous post link', 'twentythirteen' ) ); ?>
       			<?php next_post_link( '%link', _x( '%title <span class="meta-nav"><img src="/images/ArrowR.png" /></span>', 'Next post link', 'twentythirteen' ) ); ?>
   
       		</div><!-- .nav-links -->
       	</nav><!-- .navigation -->
       ?>
       ```
   
 * I’ve tried deleting various amounts of this code to see where the error is and
   can’t seem to find it. It only goes away when I delete everything between the
   opening and closing PHP code or clear that away as well. It’s still only a local
   site, so I don’t have the link to the live site yet.
 * Anyway, thanks for whatever advice you can give. I’m probably missing something
   obvious.

 * you seem to have missed to add the closing bracket and the ‘endif’ at the end
   of the second part of the code;
 * try to chnage the last few lines to:
 *     ```
       </div><!-- .nav-links -->
       	</nav><!-- .navigation -->
       	<?php
       }
       endif;

 * That was it. Works perfectly now! I knew it had to be something simple. I never
   would have known to put the endif: statement in. Thanks!
