Magento howto fetch / modify / overwrite calculation totals.phtml?

I added a product that is calculated using two attributes and uses its own estimated price. the problem is that I had to rewrite the grandiose and intermediate calculation ... for example, with the replacement of material.

Hope @stackoverflow is the magento guru who solved my problem :-)

I changed / app / design / frontend / default / gutlauf / template / checkout / cart / item / default.phtml where the layout of the cart items is done.

but now I have a problem with / app / design / frontend / default / gutlauf / template / checkout / cart / totals.phtml

<table id="shopping-cart-totals-table">
    <col />
    <col width="1" />
    <tfoot>
        <?php echo $this->renderTotals('footer'); ?>
    </tfoot>
    <tbody>
        <?php echo $this->renderTotals(); ?>
    </tbody>
</table>

How can I get my own calculation? I realized that the blocks

tax / checkout_grandtotal tax / checkout _subtotal tax / checkout_tax

/app/design/frontend/default/gutlauf/template/tax/checkout/grandtotal.phtml

<?php echo $this->helper('checkout')->formatPrice($this->getTotal()->getValue()) ?>
