Modifying Quantity Price Box

[iscatech]

Hello,

This page shows how my price box is currently displayed:
http://www.iscatech.com/ecommerce/in...roducts_id=132

This is how I would like the price box to look:


I am aware of how to change the string of header text. However, I do not know how to rearrange the items onto one row (or 4 columns). I have been editing the following code with little success:

<div id="productQuantityDiscounts">
<?php
  if ($zc_hidden_discounts_on) {
?>
  <table border="1" cellspacing="2" cellpadding="2">
    <tr>
      <td colspan="1" align="center">
      <?php echo "Price per unit"; ?>
      </td>
    </tr>
    <tr>
      <td colspan="1" align="center">
      <?php echo $zc_hidden_discounts_text; ?>
      </td>
    </tr>
  </table>
<?php } else { ?>
  <table border="1" cellspacing="2" cellpadding="2">
    <tr>
      <td colspan="<?php echo $columnCount+1; ?>" align="center">
<?php
		echo "Price per unit";
?>
      </td>
    </tr>

    <tr>
      <td align="center"><?php echo $show_qty . '<br />' . $currencies->display_price($show_price, zen_get_tax_rate($products_tax_class_id)); ?></td>

<?php
  foreach($quantityDiscounts as $key=>$quantityDiscount) {
?>
<td align="center"><?php echo $quantityDiscount['show_qty'] . '<br />' . $currencies->display_price($quantityDiscount['discounted_price'], zen_get_tax_rate($products_tax_class_id)); ?></td>
<?php
    $disc_cnt++;
    if ($discount_col_cnt == $disc_cnt && !($key == sizeof($quantityDiscount))) {
      $disc_cnt=0;
?>
  </tr><tr>
<?php
    }
  }
?>
<?php
  if ($disc_cnt < $columnCount) {
?>
    <td align="center" colspan="<?php echo ($columnCount+1 - $disc_cnt)+1; ?>">&nbsp;  </td>
<?php } ?>
    </tr>
<?php
  if (zen_has_product_attributes($products_id_current)) {
?>
    <tr>
      <td colspan="<?php echo $columnCount+1; ?>" align="center">
        <?php echo TEXT_FOOTER_DISCOUNT_QUANTITIES; ?>
      </td>
    </tr>
<?php } ?>
  </table>
<?php } // hide discounts ?>
</div>

I want to be able to format the labels to line up with the price and quantities. I am not quite sure if I am working with the correct code/file.
Any help would be appreciated. Thanks in advance.
