Can you please post your complete code? More people might be able to help, if we can see what you are trying to accomplish.

Thanks.

Also when I looked at your code and tried to make it work, I found out that you might be missing this line in your code.

<script type="text/javascript">
      google.load('visualization', '1', {packages: ['corechart']});
</script>

Give it a shot. If this does not work please post your entire code.

Regards.
