I'm curious to know if anyone else is experiencing the same problems I am.

Browser Developer Tool shows:
TypeError: objSB.appendChild is not a function

/includes/modules/pages/product_music_info/jscript_dynamic_price_updater.php #256

Code:
    function createSB()
    { // create the sidebox for the attributes info display
      if (!(document.getElementById('dynamicpriceupdatersidebox')))
      {
        var tempC = document.createElement('div');
        tempC.id = 'dynamicpriceupdatersideboxContent';
        tempC.className = 'sideBoxContent';
        tempC.innerHTML = 'If you can read this Chrome has broken something';
        objSB.appendChild(tempC);

        temp.parentNode.insertBefore(objSB, temp);
      }
    }
