X-Cart forums - Customizing & Smarty √ Having Some Problems

I am taking my first real steps at some customization of 4.3 and running into some problems. My first task was to take on the Wholesale pricing summary presented to visitors. I found the code in product_prices.tpl. The area I am looking at is:

Code:

 <table cellspacing="1" summary="{$lng.lbl_wholesale_prices}" >

   <tr class="head-row">

      <th>Quantity<br />(Packages or Items)</th>

      <th>Price</th>

    </tr>

   {foreach from=$product_wholesale item=w name=wi}

      <tr>

        <td>

          xxyyzz

          {strip}

          {$w.quantity}{if $w.next_quantity eq 0}+{elseif $w.next_quantity ne $w.quantity}-{$w.next_quantity}{/if}

          &nbsp;

          {if $w.quantity eq "1"}

            {$lng.lbl_item}

          {else}

            {$lng.lbl_items}

          {/if}

          {/strip}

        </td>

        <td>{include file="currency.tpl" value=$w.taxed_price tag_id="wp`$smarty.foreach.wi.index`"}</td>

      </tr>

    {/foreach}

  </table>

As can be seen, I inserted in the first TD box "xxyyzz" which in theory should display prior to the text in the table element.

When I view this in the browser (both IE8 and Firefox 3.5.5), I see this:

The "xxyyxx" specified does not seem to show up. Yet, if I view the source code generated by the page in the browser, it appears as below:

Code:

  <table cellspacing="1" summary="Wholesale prices" >

    <tr class="head-row">

      <th>Quantity<br />(Packages or Items)</th>

      <th>Price</th>

    </tr>

          <tr>

        <td>

          xxyyzz

          3-4&nbsp;Items

        </td>

        <td><span class="currency">$<span id="wp0">4.00</span></span></td>

      </tr>

          <tr>

        <td>

          xxyyzz

          5-9&nbsp;Items

        </td>

        <td><span class="currency">$<span id="wp1">3.50</span></span></td>

      </tr>

          <tr>

        <td>

          xxyyzz

          10+&nbsp;Items

        </td>

        <td><span class="currency">$<span id="wp2">3.00</span></span></td>

      </tr>

      </table>

Clearly, it is there in the source file, but will not display in any of my browsers.

Need some guidance here - as this one really has me confused ](*,)

Thoughts????
