[ashis.lakra]

Hi guys, Can i use 2 identical javascript codes in one single page..

The scripts are as follows in single page:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
<script type="text/javascript">
document.write(unescape("%3Cscript src='" + document.location.protocol + "//zopim.com/?m8sDhbM5dg3XlP5z4PSrMdmNXZ8QDmQf' charset='utf-8' type='text/javascript'%3E%3C/script%3E"));
</script>

<script type="text/javascript">
document.write(unescape("%3Cscript src='" + document.location.protocol + "//zopim.com/?m8sDhbM5dg3XlP5z4PSrMdmNXZ8QDmQf' charset='utf-8' type='text/javascript'%3E%3C/script%3E"));
</script>
