More than two instances of wp-polls

Hi!
I run a blog and I have your polls widget in my sidebar. Also I have fancybox on my blog. Someone recommended me to put the polls into a fancybox on my blog. So I did this:

Line 200 of footer.php

<!-- Poll it up tab -->
<a href="#fancyboxID-4">
<img class="floating_tab_poll" src="http://www.unhooked.in/wp-

content/themes/default/images/pollbtn.jpg" />
</a>
<!-- Poll it up tab ends -->

Line 896 of styles.css

.floating_tab_poll{position: fixed; left: 0; top: 50%; margin-top: -230px; }

Line 219 of header.php

<!--Subscription form for floating tab end -->
<!-- Poll it up -->
<div class="fancybox-hidden" style="display: none;">
<div id="fancyboxID-4">
<?php echo the_widget('WP_Widget_Polls'); ?>
</div>
</div>
<!-- Poll it up ends -->

Now I have two instances of the same poll on the same page. When I try to vote it says please choose a valid answer. What can I do to make it work on the sidebar widget as well as the fancybox???
