<?php
}
?>
</table>
<?php
$radio_buttons++;
}
?>
</div>
<h2><?php echo TABLE_HEADING_COMMENTS; ?></h2>
<div class="contentText">
<?php echo tep_draw_textarea_field('comments', 'soft', '60', '5', $comments); ?>
</div>
<?php
/* kgt - discount coupons Not Sure Must Check*/
if( MODULE_ORDER_TOTAL_DISCOUNT_COUPON_STATUS == 'true' ) {
?>
<h2><?php echo TABLE_HEADING_COUPON; ?></h2>
<div class="contentText">
</div>
<div class="contentText">
<?php echo ENTRY_DISCOUNT_COUPON.' '.tep_draw_input_field('coupon', '', 'size="32"', $coupon); ?>
</div>
<?php
}
/* end kgt - discount coupons */
?>
<div class="contentText">
<div style="float: left; width: 60%; padding-top: 5px; padding-left: 15%;">
<div id="coProgressBar" style="height: 5px;"></div>
