Intergrating store with web analytic tool by Raw soft

Hi Folks,

I'm integrating my store with web analytic tool. I put the following code under product.liquid file to track an event when someone view my product.

<script type="text/javascript">
  var PID = {{product.title}};

_fxm.events.push(['_fxm.ecommerce.productview', PID ]);
</script>

Above code is unable to read actual product value. It works fine when I hardcode PID value.

So i think problem actually lies when we read product title here in the code. Please help
