Maybe try this one

{if $active_modules.Extra_Fields ne ""}
{include file="modules/Extra_Fields/product.tpl"}
{foreach from=$extra_fields item=field}
 {if $field.field_value and $field.service_name eq "SERVICE_NAME15"}
  {assign name="url" value=$field.field_value}
 {/if}
 {if $field.field_value and $field.service_name eq "SERVICE_NAME13"}
  {assign name="anchor" value=$field.field_value}
 {/if}
{/foreach}
{if $url and $anchor}
 <tr>
  <td colspan="2" align="center" class="PlantBoxFooter">
   <a href="{$url}">{$anchor}</a>
  </td>
 </tr>      
{/if}
{/if}
