wrightfineart on "Embedding code from Fine Art America"

Artists on Fine Art America have been given a choice of codes to embed into different pages to show a shopping cart, including WordPress. This is an example of the code:

<script type='text/javascript' src='https://fineartamerica.com/widgetshoppingcart/widgetscripts.php'></script>
<iframe src='https://fineartamerica.com/widgetshoppingcart/widgets.php?memberidtype=artistid&memberid=33828&widgetid=5&domainid=0' style='display: inline-block; width: 300px; height: 250px; border: none;'></iframe>

When I do this and update the page, all I see is code on the page. Will the public see just the code, also? Or will they see the shopping cart?

Thank you very much.
