Changing add to cart button

[mdo82]

a while ago I changed the button "add to cart" on this page (I'm just lost the name of this page). They are both in new products, category and product listing. However, I do not remember how I got this done.

I work with two languages ​​in my shop (Dutch and English) and i'm not been able to get change this button in English.

Anyone have a tip so that i can change the button?

If i look on the source code the the code i have in dutch:

<form name="multiple_products_cart_quantity" action="http://www.nailpolishfashion.nl/index.php?main_page=index&amp;cPath=2_240&amp;language=nl&amp;sort=20a&amp;action=multiple_products_add_product" method="post" enctype="multipart/form-data"><div id="productListing">
<div class="buttonRow forward"><input type="image" src="includes/templates/simple_zen/buttons/dutch/button_add_selected.gif" alt="Geselecteerde artikelen toevoegen aan wagentje" title=" Geselecteerde artikelen toevoegen aan wagentje " id="submit1" name="submit1" /></div>
<br class="clearBoth" />

In english:

<form name="multiple_products_cart_quantity" action="http://www.nailpolishfashion.nl/index.php?main_page=index&amp;cPath=2_240&amp;sort=20a&amp;action=multiple_products_add_product" method="post" enctype="multipart/form-data"><div id="productListing">
<div class="buttonRow forward"><input class="cssButton button_add_selected" onmouseover="this.className='cssButtonHover button_add_selected button_add_selectedHover'" onmouseout="this.className='cssButton button_add_selected'" type="submit" value="Add Selected Products to Cart" style="width: 188px;" /></div>
<br class="clearBoth" />
