  <p>Please see the below product page on a live Magento website...</p>

  <p>Was working fine yesterday, this Magento site seems to have a mind of it's own currently and is proving really frustrating - I've currently got none of our developers available today to help resolve this issue on a clients website.</p>
  
  <p>Product options are not working
  Quick zoom is not working
  Add to cart is not working</p>
  
  <p>Prototype.js errors</p>
  
  <p>on page load</p>
  
  <pre><code>element.style is undefined
  var value = element.style[style];
  </code></pre>
  
  <p>selecting a product option</p>
  
  <pre><code>element.tagName is undefined
  var method = element.tagName.toLowerCase();
  </code></pre>
  
  <p>Not entirely sure if these js errors are the cause of these elements not working as I think I remember seeing them appearing in Firebug even when they were functioning correctly.</p>
  
  <p>I thought it may be due to a prototype / jquery confliction but I can't even find a jquery library on the site or being referenced - so unsure whether a noconflict var is the solution. Possible confliction with a 3rd party extension maybe?</p>
  
  <p>Would anyone be able to kindly take a look and see if you could easily identify the problem please? Thanks in advance.</p>
