想要在结帐页面添加产品数量下拉菜单：Magento

Question

I want to add a quantity drop down for the products on checkout page that user can select as much products from there. This is because i am using one page checkout and i have skipped the cart page: the product price will automatically updated when number of products selected.

I have tried this code to be added in checkout template but nothing coming up:

<select class="input-text qty" name="qty" id="qty">
    <?php $i = 1 ?>
    <?php do { ?>
    <option value="<?php echo $i?>">
        <?php echo $i?>
        <?php $i++ ?>
    </option>
    <?php } while ($i <=   (int)Mage::getModel('cataloginventory/stock_item')->loadByProduct($_product)->getQty()) ?>
</select>
