<div class="Block Moveable Panel AddToWishlistLink" id="SideProductAddToWishList" style="display:">
<div class="BlockContent">
<form name="frmWishList" id="frmWishList" action="null" method="get">
<input type="hidden" name="action" value="add" />
<input type="hidden" name="product_id" value="117" />
