Back To Product List

I have chosen a stock photo section and have created a pricelist for some images.  when you select a print size and are ready to 'add to cart' the selected print size, a 'back to product list' button is listed above the title,  and a text link is displayed below the 'add to cart button'. the top button works (YEAH) but the bottom text link 'back to product list has a code within the brackets and does not work it causes the page to freeze.

If the bottom text link is pushed the spinning wheel graphic appears and the page get forzen and does not precede 

 <a href="" onclick="backtoproductlist('dc07899b6fe60c053b89767b65b47c1c'); return false;"><span class="the-icons icon-left-open"></span>Back To Product List</a>

I have noticed that this happens also on the demo site.  I have tried using safari and chrome with the same resu

wondering if there is a fix for this
