 * The following code works if I add a value to the custom field but when I delete
   the value, instead of showing nothing, I’m left with ‘From £’.
 *     ```
       <?php
       $values = get_post_custom_values("treatment_price");
       if ( is_array($values) ) {
       echo '<h3><strong>From £' . $values[0]. '</strong></h3>';
       }
       else {
        echo '';
       }
       ?>
       ```
   
 * What’s wrong?
 * Thanks

 * Thanks for the reply, Esmi. I’m afraid it still doesn’t work for some reason.
   To clarify, I’m using:
 *     ```
       <?php
       if ( get_post_custom_values("treatment_price") ) :
       $values = get_post_custom_values("treatment_price");
       echo '<strong>£' . $values[0]. ' per treatment</strong>';
       else :
        echo '';
       endif;?>
       ```
   
 * If I enter 10 as the value, i get ‘£10 per treatment’, but then if I delete the
   10 from the field, I’m left with ‘£ per treatment’.
 * Any ideas?

 * try:
 *     ```
       <?php
       if ( !empty (get_post_custom_values("treatment_price") ) ) :
       $values = get_post_custom_values("treatment_price");
       echo '<strong>£' . $values[0]. ' per treatment</strong>';
       else :
        echo '';
       endif;?>
       ```
   
 * Works on arrays too, if that’s what being returned:
