Magento – Translation Checkout/Cart RWD Package

It appears as though OP has solved this issue:

There are a buffet of options here. This can be accomplished without a class rewrite by using a custom renderer class or renderer template. The Mage_Checkout_Block_Cart_Abstract sets the default renderer:

public function __construct()
{
    parent::__construct();
    $this->addItemRender('default', 'checkout/cart_item_renderer', 'checkout/cart/item/default.phtml');
}

Additional renderers are specified in checkout.xml:

<checkout_cart_index translate="label">
    <!-- ... -->
    <reference name="content">
        <block type="checkout/cart" name="checkout.cart">
            <action method="setCartTemplate"><value>checkout/cart.phtml</value></action>
            <action method="setEmptyTemplate"><value>checkout/cart/noItems.phtml</value></action>
            <action method="chooseTemplate"/>
            <action method="addItemRender"><type>simple</type><block>checkout/cart_item_renderer</block><template>checkout/cart/item/default.phtml</template></action>
            <action method="addItemRender"><type>grouped</type><block>checkout/cart_item_renderer_grouped</block><template>checkout/cart/item/default.phtml</template></action>
            <action method="addItemRender"><type>configurable</type><block>checkout/cart_item_renderer_configurable</block><template>checkout/cart/item/default.phtml</template></action>
     <!-- ... ->
</checkout_cart_index

It is possible to override these templates & specifications using similar directives in custom layout XML:

<checkout_cart_index>
    <action method="addItemRender" block="checkout.cart">
        <type>configurable</type>
        <block>checkout/cart_item_renderer_configurable</block
        <template>checkout/cart/item/configurable.phtml</template> <!-- custom! -->
    </action>
</checkout_cart_index>

The Mage_Catalog_Helper_Product_Configuration::getFormattedOptionValue() method is ultimately responsible for building the array which is parsed for the display - it's possible to rewrite that class method, but it would be necessary to ensure no knock-on effects exist with other types.

You can download Magento 1.4.1.1 from here then click on Release Archives tab and find the release version that you're looking for and download it, then extract it, then copy coupon.phtml from base theme app/design/frontend/base/default/template/checkout/cart/coupon.phtml to your active theme folder.

Or just copy the following code:

<form id="discount-coupon-form" action="<?php echo $this->getUrl('checkout/cart/couponPost') ?>" method="post">
    <div class="discount">
        <h2><?php echo $this->__('Discount Codes') ?></h2>
        <div class="discount-form">
            <label for="coupon_code"><?php echo $this->__('Enter your coupon code if you have one.') ?></label>
            <input type="hidden" name="remove" id="remove-coupone" value="0" />
            <div class="input-box">
                <input class="input-text" id="coupon_code" name="coupon_code" value="<?php echo $this->htmlEscape($this->getCouponCode()) ?>" />
            </div>
            <div class="buttons-set">
                <button type="button" title="<?php echo $this->__('Apply Coupon') ?>" class="button" onclick="discountForm.submit(false)" value="<?php echo $this->__('Apply Coupon') ?>"><span><span><?php echo $this->__('Apply Coupon') ?></span></span></button>
                <?php if(strlen($this->getCouponCode())): ?>
                    &nbsp; <button type="button" title="<?php echo $this->__('Cancel Coupon') ?>" class="button" onclick="discountForm.submit(true)" value="<?php echo $this->__('Cancel Coupon') ?>"><span><span><?php echo $this->__('Cancel Coupon') ?></span></span></button>
                <?php endif;?>
            </div>
        </div>
    </div>
</form>
<script type="text/javascript">
//<![CDATA[
var discountForm = new VarienForm('discount-coupon-form');
discountForm.submit = function (isRemove) {
    if (isRemove) {
        $('coupon_code').removeClassName('required-entry');
        $('remove-coupone').value = "1";
    } else {
        $('coupon_code').addClassName('required-entry');
        $('remove-coupone').value = "0";
    }
    return VarienForm.prototype.submit.bind(discountForm)();
}
