X-Cart forums - Centering Subcategories

Hi, I've been trying to center the Subcategories that are on this site which I am working on:

http://88.208.205.21/home.php?shopkey=martin
and then go to:
http://88.208.205.21/home.php?cat=253

for an example.

I edited customer/main/subcategories_t.tpl as follows (the added parts are in red):

Code:

{*

$Id: subcategories_t.tpl,v 1.7.2.2 2009/12/07 12:58:11 aim Exp $

vim: set ts=2 sw=2 sts=2 et:

*}



{section name=subcat_num loop=$subcategories}

{ if %subcat_num.first% }

<table border="0" cellspacing="5" width="100%">

{/if}



{if $smarty.section.subcat_num.index is div by 3}

</tr><tr valign="top">

{/if}



<td align="center">



{foreach from=$subcategories item=subcategory}

  <span class="subcategories" style="min-width: {$subcat_div_width+2}px; width: {$subcat_div_width}px; min-height: {$subcat_div_height}px;">

    {if $subcategory.is_icon}

      <a href="home.php?cat={$subcategory.categoryid}"><img src="{$subcategory.icon_url|amp}" alt="{$subcategory.category|escape}" width="{$subcategory.image_x}" height="{$subcategory.image_y}" /></a>

    {else}

      <img src="{$ImagesDir}/spacer.gif" alt="" width="1" height="{$subcat_img_height}" />

    {/if}



    <p><a class="subcat_desc" href="home.php?cat={$subcategory.categoryid}">{$subcategory.category|escape}</a></p>

    

 {if $config.Appearance.count_products eq "Y"}

      {if $subcategory.product_count}{$subcategory.product_count}&nbsp;{$lng.lbl_product}{if $subcategory.product_count > 1}s{/if}{/if}

     {elseif $subcategory.subcategory_count}

{$subcategory.subcategory_count}{if $subcategory.subcategory_count = 1}{$lng.lbl_subcategory}{elseif $subcategory.subcategory_count > 1}{$lng.lbl_subcategories}{/if}

    {/if}

    </span>

{/foreach}





</td>

{ if %subcat_num.last% }

</tr></table><br>

{/if}

{/section}





<div class="clearing"></div>

<br />

All the code in black is the original code.
The code I have added makes the page display the subcategories twice if there are two, or three times if there are three, etc.
I know that it needs to display all the subcategories, and I presume it comes from this code:
{foreach from=$subcategories item=subcategory}

but can anybody help me to fix this? All I want was to centre the subcategories, so that they appear like the related products, for example:

http://88.208.205.21/product.php?productid=17514&cat=262&page=1
