i need to display some more links in footer. i created those links in magento admin as static blocks (id = sample\_links ).

and then i added following code page.xml file

```
<reference name="foot_lnk">  
<block type="cms/block" name="sample_block" before="-">
      <action method="setBlockId"><block_id>sample_links</block_id></action>
    </block>
</reference>

```

i called this one in footer.phtml as,

```
<?php echo $this->getChildHtml('foot_lnk') ?>

```

but it does not display the CMS static block content. what is the issue?.
