Well you aren't even using the star rating script I suggested. You seem to have a some other star rating. You will need to add some script to update the hidden form. You would add a hidden form element to the form with the star rating system. Give it a value of 0 and an id of "hiddenFieldID".
Then use javascript to update it... something like:
<li><a href="javascript:document.getElementById('hiddenFieldID').value=1;" title="1 star out of 5" class="one-star">1</a></li>
<li><a href="javascript:document.getElementById('hiddenFieldID').value=2;" title="2 stars out of 5" class="two-stars">2</a></li>
<li><a href="javascript:document.getElementById('hiddenFieldID').value=3;" title="3 stars out of 5" class="three-stars">3</a></li>
<li><a href="javascript:document.getElementById('hiddenFieldID').value=4;" title="4 stars out of 5" class="four-stars">4</a></li>
<li><a href="javascript:document.getElementById('hiddenFieldID').value=5;" title="5 stars out of 5" class="five-stars">5</a></li>
