Styling and adding text on checkout thank u

How can I center the text and add text to the thank you page after the customer checks out? Also I would like to have the text include an option selected by the customer. For example, I have added a field that asks the customer to select the charity the a portion of their purchase to go to. I would like to have this charities name included in the text and to change per their selection.

What CSS would I use center the text on the Thank You page? Also how would I have certain text values change per customer input? I see this "s%" throughout the language edit function. Does this represent a variable if so how can I make it so that the name of the charity that the customer selects changes on the Thank You page?

It did not work for me. In place of the charity name I received the %s symbol. Here is the php code I used

?>
<?php
$orderClass = hikashop::get('class.order');
$order = $orderClass->get($order_id);
$app =& JFactory::getApplication();
$app->enqueueMessage( JText::sprintf('THANK_YOU_FOR_PURCHASE',$order->address_charity) );

Thanks

Here you go.

So what is the good word Nicholas?

The options I have for tables are address, user, product, and category. I do not have the option for "order".

Ok. For future reference when I do upgrade to the Business Edition is there a discount since I'm upgrading from the Essential version?

Cool
