I am currently using following code in node.tpl.php file:

<?php print strip_tags(render($content['field_shipping_charges'])) ?>

where in shipping_charges field I have entered following code (which I have created through admin/structure/types/manage/product/fields):

[popup title='This is popup title' text='This is popup text 1. This is popup text 2.' link=/ effect=fade]

But it is not displaying popup properly using this code -->
<?php print strip_tags(render($content['field_shipping_charges'])) ?>

Is there a way I can directly put popup tags in node.tpl.php file?
