 <p>Try to use:</p> <pre><code>jQuery(document).ready(function(){ var target = jQuery('.product-image'); target.mouseenter(function(){ jQuery(this).find('.popUpPrice button').show(); }); }); </code></pre> <p>Also <code>target</code> is already a jQuery object. You can just use <code>target.mouseenter</code> instead of <code>jQuery(target).mouseenter</code></p>
