Ps - that site I linked to is entirely open-source, so I can take its source code and use it on my own page. I'm a complete beginner, so I don't know entirely what to do, but the little message that pops up on the site is coded like this
<div id="notification"><div class="attention" style="">Success: You have added <a href="http://demo.opencart.com/index.php?route=product/product&product_id=41">iMac</a> to your <a href="http://demo.opencart.com/index.php?route=checkout/cart">shopping cart</a>!<img src="Your%20Store_files/close.png" alt="" class="close"></div></div>
I can't see on the page source how the div is told to stay hidden - does anyone know how to make a div hidden, but then become visible if if $_GET['added'] exists in the incoming URL?
Thanks a lot
