There are validation issues in your addon.

You have:

<div id="$id" class="tborder content_block">
	<h4 class="thead block_title">
		<a href="#top" class="collapse_gadget" onclick="return toggle_collapse('ads')"><img id="collapseimg_ads" src="$stylevar[imgdir_button]/collapse_generic{$vbcollapse['collapseimg_ads']}.gif" alt="" border="0" /></a>
		<a name="ads"></a>
		<span class="block_name">ADS</span>
	</h4>
	<div class="block_content" id="collapseobj_ads" style="{$vbcollapse['collapseobj_ads']}">

<div class="alt1 smallfont block_row">
		$adscode
</div>
</div>
</div>

But better would be:

<div id="ads" class="tborder content_block">
	<h4 class="thead block_title">
		<a href="#top" class="collapse_gadget" onclick="return toggle_collapse('ads')"><img id="collapseimg_ads" src="$stylevar[imgdir_button]/collapse_generic{$vbcollapse['collapseimg_ads']}.gif" alt="" border="0" /></a>
		<a name="ads"></a>
		<span class="block_name">ADS</span>
	</h4>
	<div class="block_content" id="collapseobj_ads" align="center">
	<table cellpadding="0" cellspacing="0" border="0" class="tborder" width="$stylevar[tablewidth]" align="center"> 
  <tr> 
    <td>
        <table cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%">
            <tr align="center">
              <td class="alt1">$adscode</td>
            </tr>
        </table>
    </td> 
  </tr> 
</table>
</div>
</div>
